DescripTion
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.
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 refer-
ence 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.
