INA117P-BI Datasheet PDF - TI

●DESCRIPTION

●The INA117 is a precision unity-gain difference amplifier with very high common-mode input voltage range. It is a single monolithic IC consisting of a precision op amp and integrated thin-film resistor network. It can accurately measure small differential voltages in the presence of common-mode signals up to ±200V. The INA117 inputs are protected from momentary common-mode or differential overloads up to ±500V.

●In many applications, where galvanic isolation is not essential, the INA117 can replace isolation amplifiers. This can eliminate costly isolated input-side power supplies and their associated ripple, noise and quies cent current. The INA117’s 0.001% nonlinearity and 200kHz bandwidth are superior to those of conventional isolation amplifiers.
