Product Details
The AD5751 is a single-channel, low cost, precision, voltage/current output driver with hardware or software programmable output ranges. The software ranges are configured via an SPI-/MICROWIRE™-compatible serial interface. The AD5751 targets applications in PLC and industrial process control. The analog input to the AD5751 is provided from a low voltage, single-supply digital-to-analog converter (DAC) and is internally conditioned to provide the desired output current/voltage range.
The output current range is programmable across three current ranges: 0 mA to 20 mA, 0 mA to 24 mA, or 4 mA to 20 mA.
Voltage output is provided from a separate pin that can be configured to provide 0 V to 5 V, 0 V to 10 V, and 0 V to 40 V output ranges. An overrange is available on the voltage ranges.
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 device is specified to operate with a power supply range from 10.8 V to 55 V. Output loop compliance is 0 V to AVDD − 2.75 V.
The flexible serial interface is SPI and MICROWIRE compatible and can be operated in 3-wire mode to minimize the digital isolation required in isolated applications. The interface also features an optional PEC error checking feature using CRC-8 error checking, useful in industrial environments where data communication corruption can occur.
The device also includes a power-on reset function ensuring that the device powers up in a known state (0 V or tristate) and an asynchronous CLEAR pin that sets the outputs to zero-scale/midscale voltage output or the low end of the selected current range.
An HW SELECT pin is used to configure the part for hardware or software mode on power-up.
