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 quiescent current. The INA117\x92s 0.001% nonlinearity and 200kHz bandwidth are superior to those of conventional isolation amplifiers.
The INA117 is available in 8-pin plastic mini-DIP and SO-8 surface-mount packages, specified for the \x9640°C to +85°C temperature range. The metal TO-99 models are available specified for the \x9640°C to +85°C and \x9655°C to +125°C temperature range.
