and 64V/V) -2 Option

Two Matched Programmable Gain Amplifiers

Channel-to-Channel Gain Matching of 0.1dB (Max)

Rail-to-Rail Input Range

Rail-to-Rail Output Swing

Single or Dual Supply: 2.7V to 10.5V Total

11MHz Gain Bandwidth Product

Input Noise: 10nV/√Hz

Total System Dynamic Range to 120dB

Input Offset Voltage: 2mV, Gain of 10

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.
