TDA7910

TDB7910 TDA7910 MEDIUM POWER SINGLE BIPOLAR OPERATIONAL AMPLIFIER . . . . . OUTPUT CURRENT UP TO 500 mA OFFSET VOLTAGE NULL CAPABILITY SHORT-CIRCUIT PROTECTION THERMAL OVERLOAD PROTECTION PLASTIC PACKAGE FOR EASY ASSEMBLY DESCRIPTION The TDB7910 and TDA7910 are internally compensated medium power operational amplifiers intended for use in those applications requiring load currents of several hundred milliamperes. Applications include servo amplifiers, driver interfaces, precision power comparators and motor speed control. These amplifiers are designedto operatefrom a single or dual power supplies and the input commonmode range includes the negative supply if balance inputs are tied to the negative supply. The TDB7910 and TDA7910 are thermal overload and short-circuit protected.
