The LT6372-0.2 is a gain programmable, high precision funneling instrumentation amplifier that delivers industry leading DC precision. This high precision enables smaller signals to be sensed and eases calibration requirements, particularly over temperature. The LT6372-0.2 incorporates features into the LT6370 which further improve accuracy and simplify interfacing to an ADC.The LT6372-0.2 uses a proprietary high performance bipolar process which enables industry leading accuracy coupled with exceptional long-term stability. The LT6372-0.2 is laser trimmed for very low input offset voltage (60μV) and high CMRR (80dB, G = 0.2). Proprietary on-chip test capability allows the gain drift (35ppm/°C) to be guaranteed with automated testing.The LT6372-0.2’s difference amplifier uses a split reference configuration which simplifies level shifting the amplifier’s output to the center of the ADC’s input range. Output clamp pins are also provided to limit the voltage which can be applied to an ADC’s input. EMI filtering is integrated on the LT6372-0.2’s inputs to maintain accuracy in the presence of harsh RF interference.The LT6372-0.2 is available in a compact MS16E or a 20-pin 3mm × 4mm QFN. The LT6372-0.2 is fully specified over the –40°C to 85°C and –40°C to 125°C temperature ranges.APPLICATIONSBridge AmplifierData AcquisitionThermocouple AmplifierStrain Gauge AmplifierMedical InstrumentationTransducer InterfacesDifferential to Single-Ended Conversion
