LT6372IUDC-0.2#PBF

LT®6372-0.2 is a gain programmable high precision funnelling instrumentation amplifier with level shift and output clamping that delivers industry leading DC precision. This high precision enables smaller signals to be sensed and eases calibration requirements, particularly over temperature. This incorporates features into the LT6370 which further improve accuracy and simplify interfacing to an ADC. It uses a proprietary high performance bipolar process which enables industry leading accuracy coupled with exceptional long-term stability. Its difference amplifier uses a split reference configuration which simplifies level shifting the amplifiers output to the centre of the ADCs input range. EMI filtering is integrated on its inputs to maintain accuracy in the presence of harsh RF interference. Applications are bridge amplifier, data acquisition, thermocouple amplifier, strain gauge amplifier, medical instrumentation, transducer interfaces, differential to single-ended conversion.
