Gain Amplifiers in SOT-23

FEATURES

DESCRIPTIO

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

Input Offset Voltage: 1.5mV

8-Pin Low Profile (1mm) SOT-23

(ThinSOT™) Package

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 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.
