Overview
The AD5748ACPZ from Analog Devices Inc. is a single-channel, low-cost, precision voltage/current output driver. It is designed for applications in industrial process control and programmable logic controllers (PLCs). The device features hardware or software programmable output ranges, configured via an SPI-/MICROWIRE™-compatible serial interface. It integrates an analog input from a low-voltage, single-supply digital-to-analog converter (DAC) and includes on-chip output fault detection and PEC error checking. The AD5748ACPZ is packaged in a 32-lead, 5 mm × 5 mm LFCSP package, making it suitable for a variety of industrial control environments.
