This chip offers the distinct advantages of low cost, high precision, and a programmable output range, and is widely used in industrial process control, actuator control, and programmable logic controllers (PLCs). All chips are genuine and in ample stock. We welcome inquiries and orders from both new and existing customers.
AD5749ACPZ Product Overview
The AD5749ACPZ is a single-channel, low-cost, high-precision current output driver introduced by Analog Devices. Its output range can be programmed via hardware or software, with the software output range flexibly configurable through an SPI/MICROWIRE™-compatible serial interface. Designed specifically for demanding industrial applications such as PLCs and industrial process control, this chip is a highly integrated, stable, industrial-grade current output solution.
The AD5749ACPZ’s analog input is provided by a low-voltage, single-supply digital-to-analog converter (DAC). After internal conditioning, it can output the required current/voltage range. The chip features extremely high integration, incorporating all necessary circuits internally to achieve complete, high-precision current output functionality without the need for additional external discrete components.
The AD5749ACPZ offers two programmable output current ranges: 0 mA to 24 mA and 4 mA to 20 mA. The current output features open-circuit protection and can drive a 0.1 H inductive load. The device’s supply voltage range is 10.8 V to 55 V. The output loop compliance voltage range is 0 V to AVDD − 2.75 V.
