Industrial Current/Voltage  
Output Driver,  
Programmable Ranges  
Preliminary Technical Data  
AD5750  
Voltage output is provided from a separate pin that can be  
configured to provide 0V to 5V, 0V to 10V, ±5V or ±10V  
output ranges. An over-range of 20% is available on the voltage  
ranges.  
FEATURES  
Current Output Ranges: 4–20mA, 0–20mA or 0–24mA,  
20ma, 24ma  
B Grade - 0.1% Total Unadjusted Error (TUE)  
A Grade - 0.3% Total Unadjusted Error (TUE)  
5ppm/°C Output Drift  
Analog outputs are short and open circuit protected and can  
drive capacitive loads of 1uF and inductive loads of 0.1H.  
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  
– 2.5 V.  
Voltage Output Ranges: 0-5V, 0-10V, 5V, 10V,  
20% over-range  
B Grade - 0.1% Total Unadjusted Error (TUE)  
A Grade - 0.3% Total Unadjusted Error (TUE)  
Flexible Serial Digital Interface  
On-Chip Output Fault Detection  
PEC Error Checking  
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.  
Asynchronous CLEAR Function  
Power Supply Range  
AVDD : = +12V to +24V (+/-10%)  
AVSS : = -12V to -24V (+/-10%)  
Output Loop Compliance to AVDD – 2.5 V  
Temperature Range: -40°C to +105°C  
LFCSP Packages  
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 outputs to zero-scale /  
mid-scale voltage output or the low end of the selected current  
range.  
APPLICATIONS  
A HW SELECT pin is used to configure the part for hardware  
or software mode on power up.  
Process Control  
Actuator Control  
PLC  
The total output error is typically ±0.1% in both current mode  
and voltage mode.  
GENERAL DESCRIPTION  
The AD5750 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 AD5750 targets applications in PLC and industrial process  
control. The analog input to the AD5750 is provided from a  
low voltage, single supply digital-to-analog converter and is  
internally conditioned to provide the desired output  
current/voltage range.
