The LTC6915 is a precision programmable gain instrumentation amplifier. The gain can be programmed to 0, 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, or 4096 through a parallel or serial interface. 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. The LTC6915 can be used in single power supply applications as low as 2.7V, or with dual ±5V supplies. The LTC6915 is available in a 16-lead SSOP package and a 12-lead DFN surface mount package.
