The ADF7242 is a highly integrated, low power, and high performance transceiver for operation in the global 2.4 GHz ISM band. It is designed with emphasis on flexibility, robustness, ease of use, and low current consumption. The IC supports the IEEE 802.15.4-2006 2.4 GHz PHY requirements as well as proprietary GFSK/ FSK/GMSK/MSK modulation schemes in both packet and data streaming modes. With a minimum number of external components, it achieves compliance with the FCC CFR47 Part 15, ETSI EN 300 440 (Equipment Class 2), ETSI EN 300 328 (FHSS, DR > 250 kbps), and ARIB STD T-66 standards.The ADF7242 complies with the IEEE 802.15.4-2006 2.4 GHz PHY requirements with a fixed data rate of 250 kbps and DSSS-OQPSK modulation. With its support of GFSK/FSK/GMSK/MSK modulation schemes, the IC can operate over a wide range of data rates from 50 kbps to 2 Mbps and is, therefore, equally suitable for proprietary applications in the areas of smart metering, industrial control, home and building automation, and consumer electronics. In addition, the agile frequency synthesizer of the ADF7242, together with short turnaround times, facilitates the implementation of FHSS systems.The transmitter path of the ADF7242 is based on a direct closed-loop VCO modulation scheme using a low noise fractional-N RF frequency synthesizer. The automatically calibrated VCO operates at twice the fundamental frequency to reduce spurious emissions and avoid PA pulling effects. The bandwidth of the RF frequency synthesizer is automatically optimized for transmit and receive operations to achieve optimum phase noise, modulation quality, and synthesizer settling time performance. The transmitter output power is programmable from ?20 dBm to +4 dBm with automatic PA ramping to meet transient spurious specifications. An integrated biasing and control circuit is available in the IC to significantly simplify the interface to external PAs.The receive path is based on a zero-IF architecture enabling very high blocking resilience and selectivity performance, which are critical performance metrics in interference dominated environments such as the 2.4 GHz band. In addition, the architecture does not suffer from any degradation of blocker rejection in the image channel, which is typically found in low IF receivers. In GFSK/FSK modes, the receiver features a high speed automatic frequency control (AFC) loop, which allows the frequency synthesizer to find and correct any frequency errors in the received packet.The IC can operate with a supply voltage between 1.8 V and 3.6 V with very low power consumption in receive and transmit modes while maintaining its excellent RF performance, making it especially suitable for battery-powered systems.The ADF7242 features a flexible dual-port RF interface that can be used with an external LNA and/or PA in addition to supporting switched antenna diversity.The ADF7242 incorporates a very low power custom 8-bit processor that supports a number of transceiver management functions. These functions are handled by the two main modules of the processor; the radio controller and the packet manager.See data sheet for additional information.APPLICATIONS Wireless sensor networks Automatic meter reading/Smart metering Industrial wireless control Healthcare Wireless audio/video Consumer electronics Zigbee

The ADG2108?is an analog cross point switch with anarray size of 8 ? 10. The switch array is arranged so that there are eight columns by 10 rows, for a total of 80 switchchannels. The array is bidirectional, and the rows and columns can be configured as either inputs or outputs. Each of the 80switches can be addressed and configured through the I2C compatible interface. Standard, full speed, and high speed (3.4 MHz) I2C interfaces are supported. Any simultaneous switch combination is allowed. An additional feature of the ADG2108 is that switches can be updated simultaneously,using the LDSW command. In addition, a RESET option allows all of the switch channels to be reset/off. At power on, all switches are in the off condition. The device is packaged in a 32-lead, 5 mm ? 5 mm LFCSP_VQ.APPLICATIONS AV Switching in TV Automotive Infotainment AV Receivers CCTV Ultrasound Applications KVM Switching Telecom Applications Test Equipment/Instrumentation PBX Systems

The ADG5421F is a dual SPST, low on resistance switch that features overvoltage protection, power-off protection, and overvoltage detection on the source pins. When no power supplies are present, the switch remains in the off condition, and the switch inputs are high impedance. When powered, if the analog input signal levels on either of the Sx pins exceed VDD or VSS by the threshold voltage, VT, both switches turn off together, and the open-drain fault flag (FF) pin pulls to a logic low. Input signal levels up to +60 V or ?60 V relative to ground are blocked in both the powered and unpowered condition. The switches turn on with a Logic 1 input and conduct equally well in both directions. The digital input is compatible with 1.8 V logic inputs over the full operating supply range.

The ADG5462F contains four channels that are overvoltage protected. The channel protector is placed in series with the signal path and protects sensitive components from overvoltage faults in that path. The channel protector prevents overvoltages when powered and unpowered, and it is ideal for use in applications where correct power supply sequencing cannot always be guaranteed. The primary supply voltages define the on-resistance profile, while the secondary supply voltages define the voltage level at which the overvoltage protection engages.When no power supplies are present, the channel remains in the off condition, and the channel inputs are high impedance. Under normal operating conditions, if the analog input signal levels on any Sx pin exceed positive fault voltage (POSFV) or negative fault voltage (NEGFV) by a threshold voltage (VT), the channel turns off and that Sx pin becomes high impedance. If the DR pin is driven low, the drain pin (Dx) is pulled to the secondary supply voltage that was exceeded. The output profile for each DR voltage level is shown in Figure 1. Input signal levels up to ?55 V or +55 V relative to ground are blocked in both the powered and unpowered conditions.The low on-resistance of these switches, combined with the on-resistance flatness over a significant portion of the signal range make them an ideal solution for data acquisition and instrumentation applications where excellent linearity and low distortion are critical.Product Highlights Source pins are protected against voltages greater than the secondary supply rails (POSFV and NEGFV), up to ?55 V and +55 V. In an unpowered state, source pins (Sx) are protected against voltages from ?55 V to +55 V. Overvoltage detection with digital output indicates operating state of channel. Trench isolation guards against latch-up. Optimized for low on-resistance and on-resistance flatness. The ADG5462F operates from a dual power supply range of ?5 V to ?22 V or a single power supply range of 8 V to 44 V.Applications Analog input/output modules Process control/distributed control systems Data acquisition Instrumentation Avionics Automatic test equipment Communication systems

The ADG7421F is a low voltage, dual single-pole/single-throw (SPST), low on-resistance switch that features overvoltage protection, power-off protection, and overvoltage detection on the source pins.When no power supplies are present, the switch remains in the off condition, and the switch inputs are high impedance. When powered, if the analog input signal levels on the Sx pins exceed VDD or VSS by a threshold voltage, VT, the switch automatically turns off and the digital FF (fault flag) pin drops to a logic low to indicate a fault.Input signal levels up to +60 V or ?60 V relative to ground are blocked, in both the powered and unpowered condition. The switches turn on with a Logic 1 input and conducts equally well in both directions with an analog signal range of VSS + 0.1 V to VDD ? 0.55 V for a 5 V single supply. The digital input is compatible with 1.8 V logic inputs over the full operating supply range.The ADG7421F is ideal for providing overvoltage protection for small signals such as resistance temperature device (RTD) inputs (see Figure 56 in the data sheet) and thermocouple inputs (see Figure 55). The ability to protect against high voltages up to ?60 V coupled with a low voltage supply can enable complete low voltage input stages for industrial applications.APPLICATIONS Analog input/output modules Process control/distributed control systems?
