Description
- Application Circuit is a flexible current transmitter that converts the differential voltage output from a pressure sensor to a 4 mA-to-20 mA current output. The circuit is optimized for a wide variety of bridge-based voltage or current driven pressure sensors, utilizes only five active devices and has a total unadjusted error of less than 1%. The power supply voltage can range from 7 to 36 V depending on the component and sensor driver configuration. The input of the circuit is protected for ESD and voltages beyond the supply rail, making it ideal for industrial applications
