LTC6373IDFM#PBF

LTC®6373 is a precision instrumentation amplifier with fully differential outputs which includes a closelymatched internal resistor network to achieve excellent CMRR, offset voltage, gain error, gain drift and gain nonlinearity. The user can easily program the gain to one of seven available settings through a 3bit parallel interface (A2 to A0). The LTC6373 features fully differential outputs to drive high performance, differential-input ADCs. The output common mode voltage is independently adjustable via the VOCM pin. The combination of high impedance inputs, DC precision, low noise, low distortion and high-speed differential ADC drive makes the LTC6373 an ideal candidate for optimizing data acquisition systems. It is suitable for use in data acquisition systems, biomedical instrumentation, test and measurement equipment, differential ADC drivers, single-ended-to-differential conversion, multiplexed applications.
