The LTC6910 family are low noise digitally programmable 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 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.Applications Data Acquisition Systems Dynamic Gain Changing Automatic Ranging Circuits Automatic Gain Control
