SP Amp DIFF AMP Single ±18V 8-Pin SOIC T/R

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"s 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 -40°C to +85°C temperature range. The metal TO-99 models are available specified for the -40°C to +85°C and -55°C to +125°C temperature range.
