FEATURES  
DESCRIPTIO  
The LTC®6910 family are low noise digitally program-  
mable gain amplifiers (PGAs) that are easy to use and  
occupy very little PC board space. The inverting gain is  
adjustable using a 3-bit digital input to select gains of 0, 1,  
2, 5, 10, 20, 50 and 100V/V in the LTC6910-1; 0, 1, 2, 4,  
8, 16, 32 and 64V/V in the LTC6910-2; and 0, 1, 2, 3, 4, 5,6  
and 7V/V in the LTC6910-3.  
3-Bit Digital Gain Control in Three Gain-Code  
Options  
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 Down to 8nV/Hz  
System Dynamic Range to 120dB  
The LTC6910-Xs are inverting amplifiers with rail-to-rail  
output. 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 LTC6910-X family is  
offered in an 8-lead SOT-23 package.  
Input Offset Voltage: 1.5mV
