LTC6912HGN-2#PBF

The LTC6912HGN-2#PBF is a versatile dual channel programmable gain amplifier designed for ease of use and minimal board space usage. With independently programmable gains for each channel via a simple 3-wire SPI interface, this amplifier offers voltage gains ranging from 0 to 100V/V for LTC6912-1 and 0 to 64V/V for LTC6912-2. All gains provided are inverting, allowing for flexible signal processing capabilities in a compact package
