Part No. Temp. Range Pkg. Outline Ý ELH0021K/883B b55§Ct o a125§C TO-3 MDP0003 8508801YX is the SMD version of this device. Connection Diagram 0021–1 Top View General Description The ELH0021 is a general purpose operational amplifier capa- ble of delivering large output currents not usually associated with conventional IC op amps; the ELH0021 will provide out- put currents in excess of 1A at voltage levels of g12V. In addi- tion, both the inputs and outputs are protected against over- load. The device is compensated with a single external capacitor and are free of any unusual oscillation or latch-up problems. 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 b55§Ct o a125§C. Elantec facilities comply with MIL-I-45208A and other applica- ble quality specifications. Elantec’s Military devices are 100% fabricated and assembled in our rigidly controlled, ultra-clean facilities in Milpitas, California.

The Test Level column indicates the specific device testing actually performed during production and Quality inspection. Elantec performs most electrical tests using modern high-speed automatic test equipment, specifically the LTX77 Series system. Unless otherwise noted, all tests are pulsed tests, therefore T JeTCeTA. Test Level Test Procedure I 100% production tested and QA sample tested per QA test plan QCX0002. II 100% production tested at T A e 25§C and QA sample tested at T A e 25§C, TMAX and T MIN per QA test plan QCX0002. III QA sample tested per QA test plan QCX0002. IV Parameter is guaranteed (but not tested) by Design and Characterization Data. V Parameter is typical value at T A e 25§C for information purposes only.

For supplies less than g15V, rating is equal to supply voltage. Note 2: Rating applies for ELH0021K with R SC e 0X. Note 3: Rating applies as long as package power rating is not exceeded. Note 4: Specifications apply for g5V s VS s g18V. Note 5: The ELH0021, like all Class B amplifiers, has a ‘‘dead band’’ when V OUT is near 0V. Typical values for the ‘‘dead band’’ are in the 50 mVt o2 0 0 mV range. Open-loop gain is measured at V OUT from g0.5 V DC TO g10.0 V DC which is out of the range of the ‘‘dead band’’.
