GENERAL DESCRIPTION
The AD5410/AD5420 are low cost, precision, fully integrated
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 (AV
to 60 V. Output loop compliance is 0 V to AV
The flexible serial interface is SPI, MICROWIRE™, QSPI™, and
DSP 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, 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.
