LTC6915IGN#PBF

LINEAR TECHNOLOGY  LTC6915IGN#PBF  仪器放大器, 1个放大器, 5 µV, 0.2 V/µs, 200 kHz, 2.7V 至 ± 5.5V, SSOP

The 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.
