Low Profile 10-Lead MSOP Package
The LTC
®
6911 is a family of low noise digitally program-
mable gain amplifiers (PGAs) that are easy to use and
occupy very little PC board space. The matched gain of
both channels is adjustable using a 3-bit parallel interface
to select voltage gains of 0, 1, 2, 5, 10, 20, 50 and 100V/
V (LTC6911-1) and 0, 1, 2, 4, 8, 16, 32 and 64V/V
(LTC6911-2). All gains are inverting.
The LTC6911 family consists of two matched inverting
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, the
LTC6911 family is offered in a 10-lead MSOP package.
