GENERAL DESCRIPTION

The AD5749 is a single channel, low cost, precision, current output

driver with hardware or software programmable output ranges.

The software ranges are configured via an SPI-/MICROWIRE™-

compatible serial interface. The AD5749 targets applications in

PLC and industrial process control. The analog input to the

AD5749 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.

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 and an asynchron-

ous CLEAR pin that sets the outputs to 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.

The output current range is programmable across two current

ranges: 0 mA to 24 mA, or 4 mA to 20 mA. Current output is

open-circuit protected and can drive inductive loads of 0.1 H.

The device is specified to operate with a power supply range

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
