AD694AR Description

Short technical summary and product information.

The AD694AR is a monolithic current transmitter designed to convert high level voltage input signals into a standard 4-20 mA current loop for process control applications. It offers precalibrated input ranges of 0 V to 2 V and 0 V to 10 V, selectable by pin strapping, and supports both 4-20 mA and 0-20 mA output ranges.

 

Key electrical specifications include a wide supply voltage range of 4.5 V to 36 V, a typical supply current of 23 mA, and a precision voltage reference programmable to 2.000 V or 10.000 V. The device features an open-loop alarm and an input buffer amplifier. Active laser trimming of thin film resistors ensures high accuracy without external adjustments.

 

The AD694AR is available in a 16-SOIC surface-mount package and operates over a temperature range of -40°C to 85°C. It is suitable for driving valves, actuators, and other devices in industrial control systems.
