1B31:  Wide Bandwidth Strain Gage Signal Conditioner

Product Description

The 1B31 is a high performance strain gage signal-conditioning component that offers the industry's best price/performance solution for applications involving high-accuracy interface to strain gage transducers and load cells. Packaged in a 28-pin double DIP using hybrid technology, the 1B31 is a compact and highly reliable product. Functionally, the signal conditioner consists of three sections; a precision instrumentation amplifier, a two-pole low pass filter, and an adjustable transducer excitation.
