The LTC6912 is a family of dual channel, low noise, digitally programmable gain amplifiers (PGA) that are 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, 5, 10, 20, 50, and 100V/V (LTC6912-1 ); and 0, 1, 2, 4, 8, 16, 32, and 64V/V (LTC6912-2). All gains are inverting.

The LTC6912 family consists of 2 matched amplifiers with rail-to-rail outputs. When operated with unity gain, they will also process rail-to-rail input signals. A half-supply reference generated internally at the AGND pin supports single power supply applications. Operating from single or split supplies from 2.7V to 10.5V total, the LTC6912-X family is offered in tiny SSOP and DFN-12 Packages.
