GENERAL DESCRIPTION
The AD5750/AD5750-1/AD5750-2 are single-channel, low cost,
precision voltage/current output drivers with hardware- or
software-programmable output ranges. The software ranges are
configured via an SPI-/MICROWIRE™-compatible serial interface.
The AD5750/AD5750-1/AD5750-2 target applications in PLC
and industrial process control. The analog input to the AD5750/
AD5750-1/AD5750-2 is provided from a low voltage, single-supply
digital-to-analog converter (DAC) and is internally conditioned
to provide the desired output current/voltage range. Analog input
ranges available are 0 V to 2.5 V (AD5750-1/AD5750-2) or 0 V
to 4.096 V (AD5750).
The output current range is programmable across five current
ranges: 4 mA to 20 mA, 0 mA to 20 mA, 0 mA to 24 mA, ±20 mA,
and ±24 mA. An overrange of 2% is available on the unipolar
current ranges.
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 20% is available on the voltage
ranges.
Analog outputs are short-circuit and open-circuit protected and
can drive capacitive loads of 1 µF and inductive loads of 0.1 H.
The devices are specified to operate with a power supply range
from ±12 V to ±24 V. Output loop compliance is 0 V to AVDD
2.75 V.
The flexible serial interface is SPI and MICROWIRE compatible
and can operate in 3-wire mode to minimize the digital isolation
required in isolated applications. The interface also features an
optional PEC feature using CRC-8 error checking, useful in
industrial environments where data communication corruption
can occur.
The devices also include a power-on-reset function, ensuring that
the devices power up in a known state (0 V or tristate), and an
asynchronous CLEAR pin that sets the outputs to a zero scale/mid-
scale voltage output or the low end of the selected current range.
The HW SELECT pin is used to configure the parts for hardware
or software mode on power-up.
