The LT6370 is a gain programmable, high precision 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 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 guaranteed with automated testing on the S8E package.

In addition to excellent DC specifications, the LT6370’s wide bandwidth (3.1MHz, G = 1) and fast settling time allow it to operate well in multiplexed applications. EMI filtering is integrated on the LT6370’s inputs to maintain accuracy in the presence of harsh RF interference.

The LT6370 is available in a compact 8-pin MSOP or S8E which use the conventional instrumentation amplifier pin-out as well as a 10-pin 3mm × 3mm DFN. The S8E package is also offered as an A grade which has superior DC specifications. The LT6370 is fully specified over the –40°C to 85°C and –40°C to 125°C temperature ranges.
