Description
The INA117 is a monolithic difference amplifier with the unique ability to accept up to ±200V common-mode input signals while operating on standard ±15V power supplies. Using on-chip high-voltage resistor dividers the INA117 rejects common-mode signals up to ±200V and translates a 0V to ±10V differential input signal to a 0V to ±10V ground-referenced output sign
