The OP777 , OP727 , and OP747 are precision single , dual,and quad rail-to-rail output single- supply amplifiers featuringmicropower operation and rail-to-rail output ranges. Theseamplifier s provide improved performance over the industry -standardOP07 with ±15 V supplies , and offer the further advantage of truesingle -supply operation down to 2.7 V , andsmallerpackageoptions than any other high-voltage precision bipolar amplifier.Outputs are stable with capacitive loads of over 500 pF. Supplycurrent is less than 300 μA per amplifier at 5 V. 500 Ω series resistorsprotect the inputs, allowing input signal levels several volts abovethe positive supply without phase reversal.
