LTC6912CGN-2#PBF Datasheet PDF - Linear Technology

The LTC6912CGN-2#PBF is a dual-channel low noise Programmable Gain Amplifier (PGA) with serial digital interface. It is easy to use and occupy very little PC board space. The gains for both channels are independently programmable using a 3-wire SPI interface to select voltage gains of 0, 1, 2, 4, 8, 16, 32 and 64V/V. All gains are inverting. The LTC6912 family consists of 2 matched amplifiers with rail-to-rail outputs. When operated with unity gain, it will also process rail-to-rail input signals. A half-supply reference generated internally at the AGND pin supports single power supply applications.
