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
g
12V 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

55 C to
a
125 C
