Analog Devices AD694BRZ is a monolithic current transmitter designed to accept high-level signal inputs and drive a standard 4-20 mA current loop. It is commonly used in process control to drive valves, actuators, and other control devices. Precalibrated input spans of 0 V to 2 V and 0 V to 10 V are selected by pin strapping, and other spans can be programmed with external resistors. The output stage can be configured for 4-20 mA or 0-20 mA operation.
Key electrical specifications include a wide power supply range of 4.5 V to 36 V, with single or dual supply operation. The output stage compliance extends to within 2 V of VS, and the device includes an input buffer amplifier and an open-loop alarm. Typical nonlinearity is 0.002%, and active laser trimming of thin film resistors provides high accuracy without external calibration.
The AD694BRZ is available in a 16-SOIC surface-mount package (0.295", 7.50 mm width) with 16 pins. It operates over the industrial temperature range of -40°C to 85°C. The device may be used with an optional external pass transistor to off-load power dissipation and extend the operating temperature range.
