INA105 Overview
The INA105 is a monolithic Gain = 1 differential amplifier consisting of a precision operational amplifier (op amp) and on-chip metal film resistor network. The resistors are laser trimmed for accurate gain and high mon-mode rejection. Excellent tracking of resistors (TCR) maintains gain accuracy and mon-mode rejection over temperature.
