LH0021 LH0021C 1 0 Amp Power Operational Amplifier
LH0041 LH0041C 0 2 Amp Power Operational Amplifier
General Description
The LH0021 LH0021C and LH0041 LH0041C are general
purpose operational amplifiers capable of delivering large
output currents not usually associated with conventional IC
Op Amps The LH0021 will provide output currents in ex-
cess of one ampere at voltage levels of g12V the LH0041
delivers currents of 200 mA at voltage levels closely ap-
proaching the available power supplies In addition both the
inputs and outputs are protected against overload the de-
vices are compensated with a single external capacitor and
are free of any unusual oscillation or latch-up problems
The excellent input characteristics and high output capabili-
ty of the LH0021 make it an ideal choice for power applica-
tions such as DC servos capstan drivers deflection yoke
drivers and programmable power supplies
The LH0041 is particularly suited for applications such as
torque driver for inertial guidance systems diddle yoke driv-
er for alpha-numeric CRT displays cable drivers and pro-
grammable power supplies for automatic test equipment
The LH0021 is supplied in a 8 pin TO-3 package rated at 20
watts with suitable heatsink The LH0041 is supplied in both
12 pin TO-8 (2 5 watts with clip on heatsink) and a power 8
pin ceramic DIP (2 watts with suitable heatsink) The
LH0021 and LH0041 are guaranteed over the temperature
range of b55 C to a125 C while the LH0021C and
LH0041C are guaranteed from b25 C to a85 C
