GENERAL DESCRIPTION
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
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 F.
The device operates with an AVDD power supply range from
10.8 V to 40 V. Output loop compliance 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.
