• description

  The LTC®6915 is an accurate programmable gain amplifier. The gain can be set to 0, 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, or 4096 via a parallel or serial interface. With a single 5V supply and any set gain, the CMRR is typically 125dB. Voltage offset less than 10uV and temperature drift less than 50nV/°C.

  LTC6915 A differential input voltage is converted into a single-ended signal using charge balance sampling data technology, which is then amplified by a zero-drift op-amp.

  The differential input operates from rail to rail, while the single-ended output oscillates from rail to rail. LTC6915 can be used in single-supply applications as low as 2.7V or in applications with dual ±5V supplies. LTC6915 is available in a 16-lead SSOP package and a 12-lead DFN surface-mount package.
