The LTC
6912 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.
