Industry's Most Accurate Voltage/Current Output Drivers for Industrial Control Systems

iCMOSThe AD5750 and AD5751 are single-channel, high performance, voltage/current output drivers with hardwareprogrammable or software-programmable output ranges. The AD5750 operates from industry-standard ±12 V to ±24 V supplies and delivers 5 ppm/°C output drift, 0.01% linearity, and 0.1% TUE. The output configuration is software-selectable from options of 5 V, 10 V, ±5 V, and ±10 V in voltage mode; and 4 mA to 20 mA, 0 mA to 20 mA, 0 mA to 24 mA, ±20 mA, and ±24 mA in current mode.

All output spans include an additional overrange setting. Analog outputs are short-circuit and open-circuit protected, and can drive capacitive loads of 1 µF and inductive loads of 0.1 H. The flexible serial interface is SPI-compatible and features an optional PEC error checking feature using CRC-8 error checking. The device also includes an asynchronous CLEAR pin that sets the outputs to zero-scale/midscale in voltage mode or the low end of the selected current range in current mode. The AD5751 operates with single supplies of 12 V to 60 V, and features unipolar voltage and current mode output configurations. Both devices are specified over the –40°C to +105°C extended industrial temperature range and are housed in a 5 mm × 5 mm LFCSP package. Chip fabrication is on ADI's iCMOS process technology.
