Overview
The LTC6800HMS8#TRPBF, produced by Analog Devices Inc., is a precision instrumentation amplifier designed for high-accuracy signal processing. This amplifier is notable for its high common-mode rejection ratio (CMRR) of typically 116dB, which remains independent of the gain setting. It operates with a single supply voltage ranging from 2.7V to 5.5V and is available in both MS8 surface mount and 3mm × 3mm × 0.8mm dual fine pitch leadless (DFN) packages, making it suitable for a variety of applications where space is limited.
