Digitally Calibrated Bridge Sensor Signal Conditioner with 4mA to 20mA Current Loop Output
参考設計 著者: Texas Instruments
Digitally calibrated bridge sensor signal conditioner with 4mA to 20mA current loop output. 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
