1B32:  Bridge Transducer Signal Conditioner

Product Description

Model 1B32 is a precision, chopper-based, signal-conditioning component ideally suited for high accuracy applications of load cells and bridge transducers. Packaged in a compact 28-pin plastic double DIP, the 1B32 takes advantage of hybrid technology for high reliability as well as higher channel density. Functionally, the signal conditioner consists of three basic parts: a high performance chopper-based amplifier, a low-pass filter and an adjustable transducer excitation source.
