ICH8510

The ICH8510 is a family of hybrid power amplifiers that have been specifically designed to drive linear and rotary actuators,electronic valves,push-pull solenoids,and DC & AC motors.There are three models available for up to +30V power supply operation:2.7 amps @ 24 volt output levels,2 amps @ 24V and 1 amp @ 24V.All amplifiers are protected against shorts to ground by the addition of 2 external protection resistors.For a device operating at lower voltages,see the ICH8515 data sheet.The design uses a conventional 741 operational amplifier,a special monolithic driver chip,NPN & PNP power transistors,and internal frequency compensating capacitors.The chips are mounted on a berllium oxide substrate for optimum heat transfer to the metal package.This substrate also provides electrical isolation between amplifiers and metal package.The IC power driver chip has built-in regulators that provide the 741 with typically a ±13V supply.

The ICH8510 has 9 features.The first one is delivers up to 2.7 Amps @ 24-28V DC (30V supplies).The second one is protected against inductive kick back with internal power limiting.The third one is programmable current limiting (short circuit protection).The fourth one is package is electrically isolated (allowing easy heat sinking).The fifth one is open loop DC gain > 100dB.The sixth one is 20mA typical standy quiescent current.The seventh one is popular 8 pin TO-3 package.The eighth one is internal frequency compensation.The ninth one is can drive up to 0.1 horsepower motors.
