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§Ctoa
125§C.
