GENERAL DESCRIPTION
The AD5410/AD5420 is a low-cost, precision, fully integrated
12/16-bit converter offering a programmable current source
output designed to meet the requirements of industrial process
control applications.The output current range is programmable
to 4mA to 20 mA, 0mA to 20mA or an over range function of
0mA to 24mA. The output is open circuit protected and can
drive inductive loads of 1H. The device is specified to operate
with a power supply range from 10.8 V to 40V
AD5410/AD5420AREZ) or 10.8V to 60V
(AD5410/AD5420ACPZ). Output loop compliance is 0 V to
AV
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 and an
asynchronous CLEAR pin which sets the output to the low end
of the selected current range.
The total output error is typically ±0.1% FSR.
