High Common-Mode Voltage DIFFERENCE …
INA117 FEATURES Common-Mode INPUT RANGE: 200V (VS = 15V) PROTECTED INPUTS: 500V Common-Mode 500V Differential UNITY GAIN: Gain Error max NONLINEARITY: max CMRR: 86dB minAPPLICATIONS CURRENT MONITOR BATTERY CELL- Voltage MONITOR GROUND BREAKER INPUT PROTECTION SIGNAL ACQUISITION IN NOISYENVIRONMENTS FACTORY AUTOMATIONDESCRIPTIONThe INA117 is a precision unity-gain differenceamplifier with very high Common-Mode input voltagerange. It is a single monolithic IC consisting of aprecision op amp and integrated thin-film resistornetwork. It can accurately measure small differentialvoltages in the presence of Common-Mode signals upto 200V. The INA117 inputs are protected frommomentary Common-Mode or differential overloadsup to many applications, where galvanic isolation is notessential, the INA117 can replace isolation can eliminate costly isolated input-side powersupplies and their associated ripple, noise and quies-cent current.
INA117 SBOS154A 4 TYPICAL PERFORMANCE CURVES At TA = +25°C, VS = ±15V, unless otherwise noted. POSITIVE COMMON-MODE VOLTAGE RANGE vs POSITIVE POWER-SUPPLY VOLTAGE Positive Power-Supply Voltage (V)
