Demonstration circuit 932A is an adjustable 1A linear regulator featuring LT3022. The LT3022 is a very low dropout voltage (VLDO™) linear regulator that operates from input supplies down to 0.9V. The device supplies 1A of output current with 145mV typical dropout voltage. The LT3022 is ideal for low input voltage to low output voltage applications, providing comparable electrical efficiency to a switching regulator. The demo board has an input voltage range from 1V to 10V and provides a jumper-selectable output voltage of 0.9V, 1V, 1.2V, 1.5V, 1.8V or a user-defined value down to 200mV. The regulator optimizes stability and transient response with low ESR ceramic output capacitors as small as 10µF. Other LT3022 features include 0.05% typical line regulation and 0.05% typical load regulation. In shutdown, the quiescent current typically drops to 7.5µA. Internal protection circuitry includes reverse-battery protection, current limiting, thermal limiting with hysteresis and reverse-current protection.

The LTC2609/LTC2619/LTC2629 are quad 16-, 14- and 12- bit, 2.7V to 5.5V rail-to-rail voltage output DACs in a 16?lead SSOP package. They have built-in high performance output buffers and are guaranteed monotonic.These parts establish new board-density benchmarks for 16- and 14-bit DACs and advance performance standards for output drive and load regulation in single-supply, voltage- output DACs.The parts use a 2-wire, I2C compatible serial interface. The LTC2609/LTC2619/LTC2629 operate in both the standard mode (clock rate of 100kHz) and the fast mode (clock rate of 400kHz).The LTC2609/LTC2619/LTC2629 incorporate a power-on reset circuit. During power-up, the voltage outputs rise less than 10mV above zero-scale; after power-up, they stay at zero-scale until a valid write and update take place. The power-on reset circuit resets the LTC2609-1/LTC2619?1/ LTC2629-1 to mid-scale. The voltage outputs stay at midscale until a valid write and update take place.Applications Mobile Communications Process Control and Industrial Automation Automatic Test Equipment and Instrumentation

The ADF7021 is a low power, highly integrated 2FSK/3FSK/4FSK transceiver. It is designed to operate in the narrowband, license-free ISM bands and licensed bands in the 80 MHz to 650 MHz and 862 MHz to 940 MHz frequency ranges. It has both Gaussian and raised cosine data filtering options to improve spectral efficiency for narrowband applications.It is suitable for circuit applications targeted at European ETSI-EN 300-220, the Japanese ARIB STD-T67, the Chinese Short Range Device regulations, and the North American FCC Part 15, Part 90, and Part 95 regulatory standards. A complete transceiver can be built using a small number of external discrete components, making the ADF7021 very suitable for price-sensitive and area-sensitive applications.The transmit section contains a voltage controlled oscillator (VCO) and a low noise fractional-N PLL with output resolution of <1 ppm. This frequency-agile PLL allows the ADF7021 to be used in frequency hopping spread spectrum (FHSS) systems. The VCO operates at twice the fundamental frequency to reduce spurious emissions and frequency pulling problems. The transmitter output power is programmable in 63 steps from ?16 dBm to +13 dBm and has an automatic power ramp control to prevent spectral splatter and help meet regulatory standards. The transceiver RF frequency, channel spacing, and modulation are programmable using a simple 3-wire interface. The device operates with a power supply range of 2.3 V to 3.6 V and can be powered down when not in use.A low IF architecture is used in the receiver (100 kHz), minimizing power consumption and the external component count while avoiding interference problems at low frequencies. The IF filter has programmable bandwidths of 12.5 kHz, 18.75 kHz, and 25 kHz. The ADF7021 supports a wide variety of programmable features including Rx linearity, sensitivity, and IF bandwidth, allowing the user to trade off receiver sensitivity and selectivity against current consumption, depending on the application. The receiver also features a patent-pending automatic frequency control (AFC) loop with programmable pull-in range, allowing the PLL to track out the frequency error in the incoming signal.An on-chip ADC provides readback of an integrated temperature sensor, an external analog input, the battery voltage, and the RSSI signal, which provides savings on an ADC in some applications. The temperature sensor is accurate to ?10?C over the full operating temperature range of ?40?C to +85?C. This accuracy can be improved by doing a 1-point calibration at room temperature and storing the result in memory.

The ADF7024 is an ultralow power, integrated transceiver for use in the license-free ISM bands at 433 MHz, 868 MHz, and 915 MHz. Its ease of use and high performance make it suitable for a wide variety of wireless applications. The ADF7024 is suitable for operation under the European ETSI EN 300-220 regulation, the North American FCC Part 15 regulation, and other similar regulatory standards.The ADF7024 can operate under a number of predefined radio profiles. For each radio profile, optimized register settings are provided for the ADF7024 radio. This ensures that the RF communication layer works seamlessly, allowing the user to concentrate on the protocol and system level design and prototyping. The radio profiles cover common data rate and modulation options. There are six radio profiles in total, as shown in Table 1.The ADF7024 operates with a power supply range of 2.2 V to 3.6 V and has very low power consumption in both Tx and Rx modes, enabling long lifetimes in battery-operated systems while maintaining excellent RF performance.The low IF receiver minimizes power consumption and provides excellent sensitivity. The receiver is exceptionally linear and, therefore, is very resilient to the presence of interferers in spectrally noisy environments. The highly efficient transmitter has programmable output power up to 13.5 dBm and automatic power amplifier (PA) ramping to meet transient spurious specifications. The RF synthesizer comprises a voltage controlled oscillator (VCO), a low noise fractional-N phase-locked loop (PLL) and a loop filter, all of which are fully integrated and automatically calibrated. This agile frequency synthesizer facilitates the implementation of frequency-hopping spread spectrum (FHSS) systems.The smart wake mode (SWM) allows the ADF7024 to wake up autonomously from sleep using the internal wake-up timer without intervention from the host processor. This functionality allows carrier sense, packet sniffing, and packet reception while the host processor is in sleep, thereby reducing overall system current consumption.The ADF7024 eases the processing burden of the host processor by integrating the lower layers of a typical communication protocol stack. The host processor can configure the ADF7024 using a simple command-based protocol over a standard 4-wire SPI interface. A single-byte command transitions the radio between states or performs a radio function.A complete wireless solution can be built using a small number of external discrete components and a host processor (typically a microcontroller).For more information, see the ADF7024 Hardware Reference Manual, UG-698, which is only available as part of the ADF7024 design resource package.APPLICATIONS Wireless sensor networks (WSNs) Home and building automation Asset tracking Process and building control Industrial control Internet of Things (IoT)
