This high precision enables smaller signals to be sensed and eases calibration requirements, particularly over temperature. The LT6370 uses a proprietary high performance bipolar process which enables industry leading accuracy coupled with exceptional long-term stability. The LT6370 is laser trimmed for very low input offset voltage (25µV) and high CMRR (94dB, G = 1). Proprietary on-chip test capability allows the input offset voltage drift (0.3µV/°C) and gain drift (30ppm/°C) to be guarantee...
