The is a high performance wide bandwidth strain gage Signal Conditioner IC that offers the industries best price/performance solution for applications involving high-accuracy interface to strain gage transducers and load cells. Functionally, the signal conditioner consists of three sections a precision instrumentation amplifier, a two-pole low pass filter and an adjustable transducer excitation. The instrument amplifier IA section features low input offset drift of ±0.25µV/°C RTI, G=1000V/V and excellent nonlinearity of ±0.005% maximum. In addition, the IA exhibits low noise of 0.3µV p-p type 0.1 to 10Hz and outstanding 140dB minimum common mode rejection G=1000V/V, 60Hz. The gain is programmable from 2V/V up to 5000V/V one external resistor.
