LTC6915HGN#PBF

LTC6915 is a zero drift, precision, instrumentation amplifier with digitally programmable gain. It uses charge balanced sampled data techniques to convert a differential input voltage into a single ended signal that is in turn amplified by a zero-drift operational amplifier. The differential inputs operate from rail-to-rail and the single-ended output swings from rail-to-rail. This device can be used in single power supply applications as low as 2.7V, or with dual ±5V supplies. It is widely used in application such as thermocouple amplifiers, electronic scales, medical instrumentation, strain gauge amplifier, high resolution data acquisition etc.
