DESCRIPTION

The INA149 is a precisionunity-gain differenceamplifier with a very highinput common-modevoltage range. lt is a single, monolithic device thatconsists of a precision op amp and an integrated thin.film resistor network. The INA149 can accuratelymeasure small differential voltages in the presence ofcommon-mode signals up to +275 V. The INA149inputs are protected from momentary common-modeor differential overloads of up to 500 V.
In many applications, where galvanic isolation in notrequired, the INA149 can replace isolation amplifiers.This ability can eliminate costly isolated input sidepower supplies and the associated ripple, noise, andquiescent current. The excellent 0.0005% nonlinearityand 500-kHz bandwidth of the INA149 are superior tothose of conventional isolation amplifiers.
The INA149 is pin-compatible with the INA117 andINA148 type high common-mode voltage amplifiersand offers improved performance over both devices.The INA149 is available in the solC-8 package withoperation specified over the extended industrialtemperature range of -40°C to +125C.
