GENERAL DESCRIPTION
12-/16-bit converters offering a programmable current source
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 output is open-circuit protected. The device
operates with a power supply (AVDD) range from 10.8 V to
60 V. Output loop compliance is 0 V to AVDD 2.5 V.
The flexible serial interface is SPI, MICROWIRE, QSPI, and
DSP compatible and can be operated in 3-wire mode to mini-
mize 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, and an asynchronous
CLEAR pin that sets the output to the low end of the selected
current range.
The total unadjusted error is typically ±0.01% FSR.
