INA149AIDR is a type of high common-mode voltage difference amplifier composed of a precision op amp and an integrated thin-film resistor network. It can replace isolation amplifiers in many applications requiring no galvanic isolation. As a result, It is able to eliminate costly isolated input side power supplies and the associated ripple, noise, and quiescent current.
