LTC6800 - Rail-to-Rail, Input and Output, Instrumentation Amplifier

The LTC6800 is a precision instrumentation amplifier. The CMRR is typically 116dB with a single 5V supply and is independent of gain. The input offset voltage is guaranteed below 100μV with a temperature drift of less than 250nV/°C. The LTC6800 is easy to use; the gain is adjustable with two external resistors, like a traditional op amp.

The LTC6800 uses charge balanced sampled data techniques to convert a differential input voltage into a single ended signal that is in turn amplified by a zero-drift operational amplifier.

The differential inputs operate from rail-to-rail and the single ended output swings from rail-to-rail. The LTC6800 is available in an MS8 surface mount package. For space limited applications, the LTC6800 is available in a 3mm × 3mm × 0.8mm dual fine pitch leadless package (DFN).
