description
The LTC®6910 series is a low-noise digital programmable gain amplifier (PGA) that takes up very little printed board space and is easy to use. The reversed-phase gain is adjustable, with a choice of gains of 0, 1, 2, 5, 10, 20, 50, and 100V/V in LTC6910-1 when a 3-digit input is used; In LTC6910-2, you can choose from gains of 0, 1, 2, 4, 8, 16, 32, and 64V/V; In LTC6910-3, gains of 0, 1, 2, 3, 4, 5, 6, and 7V/V are selectable.
The LTC6910-X series is an inverting amplifier with rail-to-rail output. When operating under unit gain conditions, they also process rail-to-rail input signals. An internally generated half-power reference located on the AGND pin supports single-supply applications. The LTC6910-X series operates from 2.7V to 10.5V in single or split supply conditions and is available in an 8-pin SOT-23 package.
