1 Amp Power Operational Amplifier Features General Description # High output current1.2A # Large output voltage swing g 12V # Low standby power100 mW # Wide full power bandwidth20 kHz # Low input bias current # Low input offset voltage # High open-loop gain l 100 dB # MIL-STD-883 devices 100% manufactured in U.S.A. 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 and are free of any unusual oscillation or latch-up problems. Ordering Information Part No. Temp. Range Pkg. OutlineY ELH0021K/883B b 55 C to a 125 C TO-3 MDP0003 8508801YX is the SMD version of this device. Connection Diagram ELH0021K/883/8508801YX ELH0021K/883/8508801YX The 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 programmable power supplies. Other applications include torque drivers for inertial guidance systems, diddle yoke drivers for alphanumeric CRT displays, cable drivers, and programmable power supplies for automatic test equipment. The 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. Elantec 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.
