TIPD126: Bridge Sensor Conditioner

Summary

This bridge sensor conditioner module delivers a well regulated current output to a ground-referenced load. The first stage uses a mixed-signal programmable gain amplifier (PGA) to provide linearization and temperature compensation to a differential bridge sensor voltage. The second stage converts the PGA output voltage into current and transmits the current over a standard 4 mA to 20 mA current loop.

Additional circuitry protects the module against electrostatic discharge (ESD), electrical fast transients
(EFT), radiated and conducted electromagnetic interference (EMI), and surge.

TI Precision Designs are analog solutions created by TI’s analog experts. CerTIfied Designs offer the theory, component selection, simulation, complete PCB schematic & layout, bill of materials, measured performance, and certification testing results of useful circuits. Circuit modifications that help to meet alternate design goals are also discussed.
