The AD5755-1 is a quad, voltage and current output digital-to-analog converter (DAC) that operates with a power supply range from −26.4 V to +33 V. On-chip dynamic power control minimizes package power dissipation in current mode. This is achieved by regulating the voltage on the output driver from 7.4 V to 29.5 V using a dc-to-dc boost converter optimized for minimum on-chip power dissipation. Each channel has a corresponding CHART pin so that HART signals can be coupled onto the current output of the AD5755-1.The device uses a versatile 3-wire serial interface that operates at clock rates of up to 30 MHz and is compatible with standard SPI, QSPI™, MICROWIRE™, DSP, and microcontroller interface standards. The interface also features optional CRC-8 packet error checking, as well as a watchdog timer that monitors activity on the interface.PRODUCT HIGHLIGHTS Dynamic power control for thermal management. 16-bit performance.

The ADM1168 Super Sequencer® is a configurable supervisory/ sequencing device that offers a single-chip solution for supply monitoring and sequencing in multiple supply systems.The device also provides up to eight programmable inputs for monitoring undervoltage faults, overvoltage faults, or out-of-window faults on up to eight supplies. In addition, eight programmable outputs can be used as logic enables. Six of these programmable outputs can also provide up to a 12 V output for driving the gate of an NFET that can be placed in the path of a supply.The logical core of the device is a sequencing engine. This state machine-based construction provides up to 63 different states. This design enables very flexible sequencing of the outputs based on the condition of the inputs.A block of nonvolatile EEPROM is available that can be used to store user-defined information and may also be used to hold a number of fault records that are written by the sequencing engine defined by the user when a particular fault or sequence occurs.The ADM1168 is controlled via configuration data that can be programmed into an EEPROM. The whole configuration can be programmed using an intuitive GUI-based software package provided by Analog Devices, Inc.For more information about the ADM1168 register map, refer to the AN-721 Application Note.APPLICATIONS Central office systems Servers/routers Multivoltage system line cards DSP/FPGA supply sequencing In-circuit testing of margined supplies

The AD4001/AD4005 are high accuracy, high speed, low power, 16-bit, Easy Drive, precision successive approximation register (SAR) analog-to-digital converters (ADCs) that operate from a single power supply, VDD. The reference voltage, VREF, is applied externally and can be set independent of the supply voltage. The AD4001/AD4005 power scales linearly with throughput. Easy Drive features reduce both signal chain complexity and power consumption while enabling higher channel density. The reduced input current, particularly in high-Z mode, coupled with a long signal acquisition phase, eliminates the need for a dedicated ADC driver. Easy Drive broadens the range of companion circuitry that is capable of driving these ADCs (see Figure 2 in the data sheet).Input span compression eliminates the need to provide a negative supply to the ADC driver amplifier while preserving access to the full ADC code range. The input overvoltage clamp protects the ADC inputs against overvoltage events, minimizing disturbances on the reference pin and eliminating the need for external protection diodes. Fast device throughput up to 2 MSPS allows users to accurately capture high frequency signals and to implement oversampling techniques to alleviate the challenges associated with antialias filter designs. Decreased serial peripheral interface (SPI) clock rate requirements reduce digital input and output power consumption, broadens digital host options, and simplifies the task of sending data across digital isolation. The SPI-compatible serial user interface is compatible with 1.8 V, 2.5 V, 3 V, and 5 V logic by using the separate VIO logic supply.APPLICATIONS Automated test equipment Machine automation Medical equipment Battery-powered equipment Precision data acquisition systems Instrumentation and control systems
