FEATURES  
DESCRIPTIO  
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.  
3-Bit Digital Gain Control:  
(Inverting Gains of 0, 1, 2, 5, 10, 20, 50  
and 100V/V) -1 Option  
(Inverting Gains of 0, 1, 2, 4, 8, 16, 32  
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  
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.  
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
