Industrial Current/Voltage Output Driver  
with Programmable Ranges  
AD5750/AD5750-1  
The output current range is programmable across five current  
ranges: 4 mA to 20 mA, 0 mA to 20 mA or 0 mA to 24 mA,  
FEATURES  
Current output ranges: 4 mA to 20 mA, 0 mA to 20 mA or  
0 mA to 24 mA, ±20 mA, and ±24 mA  
±0.03% FSR total unadjusted error (TUE)  
±± ppm/°C typical output drift  
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.  
Voltage output ranges: 0 V to ± V, 0 V to 10 V, ±± V, and ±10 V,  
with 20% overrange  
±0.02% FSR TUE  
±3 ppm/°C typical output drift  
Flexible serial digital interface  
On-chip output fault detection  
PEC error checking  
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 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.  
Asynchronous CLEAR function  
Flexible power-up condition to 0 V or tristate  
Power supply range  
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.  
AVDD: +12 V (± 10%) to +24 V (± 10%)  
AVSS: −12 V (± 10%) to −24 V (± 10%)  
Output loop compliance to AVDD − 2.7± V  
Temperature range: −40°C to +10±°C  
32-lead, ± mm × ± mm LFCSP package  
The device also includes a power-on reset function, ensuring  
that the device powers up in a known state (0 V or tristate),  
and an 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  
The AD5750/AD5750-1 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 target applications in PLC and industrial  
process control. The analog input to the AD5750/AD5750-1  
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) or 0 V to 4.096 V (AD5750).
