General Description
The ELH0021 is a general purpose operational amplifier capable of delivering large output currents not usually associated with conventional IC op amps the ELH0021 will provide output currents in excess of 1A at voltage levels of g 12V In addition both the inputs and outputs are protected against overload The device is compensated with a single external capacitor T and are free of any unusual oscillation or latch-up problems he excellent input characteristics and high output capability of the ELH0021 make it an ideal choice for power applications such as DC servos capstan drivers deflection yoke drivers and O programmable power supplies ther applications include torque drivers for inertial guidance c systems diddle yoke drivers for alphanumeric CRT displays able drivers and programmable power supplies for automatic T test equipment he ELH0021 is supplied in an 8-pin TO-3 package rated at 20W with suitable heatsink The ELH0021 is guaranteed over the temperature range of b 55 C to a 125 C E lantec facilities comply with MIL-I-45208A and other applicable quality specifications Elantec's Military devices are 100% fabricated and assembled in our rigidly controlled ultra-clean facilities in Milpitas California For additional information on Elantec's Quality and Reliability Assurance policy and proceE res request brochure QRA-1 du
