LTC6910-1 LTC6910-2/LTC6910-3 Digitally Controlled Programmable Gain Amplifiers in SOT-23 FEATURES s s s s s s s s s 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 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. , LTC and LT are registered trademarks of Linear Technology Corporation.
