GENERAL DESCRIPTION
The AD5412/AD5422 are low cost, precision, fully integrated
12-/16-bit digital-to-analog converters (DAC) offering a pro-
grammable current source and programmable voltage output
designed to meet the requirements of industrial process control
applications.
The output current range is programmable at 4 mA to 20 mA,
0 mA to 20 mA, or an overrange function of 0 mA to 24 mA.
The LFCSP version of this product has a CAP2 pin so that the
HART signals can be coupled onto the current output of the
AD5412/AD5422.
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 10% is available on all ranges.
Analog outputs are short and open-circuit protected and can
drive capacitive loads of 1 µF.
The device operates with an AVDD power supply range from 10.8 V
to 40 V. Current loop compliance voltage is 0 V to AVDD − 2.5 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 device also includes a power-on-reset function, ensuring
that the device powers up in a known state. The part also includes
an asynchronous clear pin (CLEAR) that sets the outputs to
zero-scale/midscale voltage output or the low end of the
selected current range.
The total output error is typically ±0.01% in current mode and
±0.01% in voltage mode.
