Industrial Current/Voltage Output Driver

with Programmable Ranges

AD5748

The output current range is programmable across two current

ranges: 4 mA to 21 mA and 0 mA to 21 mA.

FEATURES

Current output ranges: 4 mA to 21 mA, 0 mA to 21 mA

0.15% FSR total unadjusted error (TUE)

5 ppm/°C FSR typical output drift

Voltage output ranges: 0 V to 5 V, 0 V to 10.5 V, 10.5 V

0.05% FSR total unadjusted error (TUE)

3 ppm/°C FSR output drift

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.

Flexible serial digital interface

On-chip output fault detection

PEC error checking

The device is specified to operate with a power supply range from

12 V to 24 V. Output loop compliance is 0 V to AV_DD− 2.75 V.

Asynchronous CLEAR function

Flexible power-up condition to 0 V or tristate

Power supply range

AV_DD: +12 V ( 10%) to +24 V ( 10%)

AV_SS: −12 V ( 10%) to −24 V ( 10%)

Output loop compliance to AV_DD− 2.75 V

Temperature range: −40°C to +105°C

32-lead, 5 mm × 5 mm LFCSP package

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.

APPLICATIONS

Process control

Actuator control

PLCs

An HW SELECT pin is used to configure the part for hardware

or software mode on power-up.

GENERAL DESCRIPTION

Note that the plots in the Typical Performance Characteristics

section of this data sheet contain information on the standard

ranges, as released in the AD5750/AD5750-1 data sheet. Although

the overranges have been tested, new plots were not generated

and substitution data was used for plotting purposes.

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.
