GENERAL DESCRIPTION
The AD5748 is a single-channel, low cost, precision, voltage/
current output driver with hardware or software programmable
output ranges. The software ranges are configured via an SPI-/
MICROWIRE-compatible serial interface. The AD5748 targets
applications in PLC and industrial process control. The analog
input to the AD5748 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. The analog
input range is 0 V to 4.096 V.
The output current range is programmable across two current
ranges: 4 mA to 21 mA and 0 mA to 21 mA.
Voltage output is provided from a separate pin that can be
configured to provide 0 V to 5 V, 0 V to 10.5 V, or ±10.5 V
output range.
Analog outputs are short-circuit and open-circuit protected and
can drive capacitive loads of 2 μF and inductive loads of 0.1 H.
The device is 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 be operated in 3-wire mode to minimize the digital
isolation required in isolated applications. The interface also
features an optional PEC error checking feature using CRC-8
error checking, useful in industrial environments where data
communication corruption can occur.
The device also includes a power-on-reset function, ensuring
that the device powers up in a known state (0 V or tristate),
and a asynchronous CLEAR pin that sets the outputs to zero
scale/midscale voltage output or the low end of the selected
current range.
An HW SELECT pin is used to configure the part for hardware
or software mode on power-up.
Note that the plots in the Typical Performance Characteristics
section of this data sheet contain information on the standard
the overranges have been tested, new plots were not generated
and substitution data was used for plotting purposes.
