The LTC6915CGN#PBF is a precision Instrumentation Amplifier with digitally programmable gain. The CMRR is typically 125dB with a single 5V supply with any programmed gain. The offset is below 10μV with a temperature drift of less than 50nV/°C. The LTC6915 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.
Rail-to-rail input
Parallel or serial (SPI) interface for gain setting
