TEXAS INSTRUMENTS INA117KUG4 差分放大器, 高共膜电压, 1 放大器, 1 mV, 1 dB, 200 kHz, -40 °C, 85 °C
The 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.
