The AD5750 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 AD5750 targets
applications in PLC and industrial process control. The analog
input to the AD5750 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 analog
input range is 0 V to 4.096 V.
The output current range is programmable across five current
ranges: 4 mA to 20 mA, 0 mA to 20 mA or 0 mA to 24 mA,
±20 mA, and ±24 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, ±5 V, or
±10 V output ranges. An overrange of 20% is available on the
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
±12 V to ±24 V. Output loop compliance is 0 V to AV
− 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
A HW SELECT pin is used to configure the part for hardware
or software mode on power-up.
