Operational Amplifier
General Description
The LH0020/LH0020C is a general purpose opera·
tional amplifier designed to source and sink 50 mA
output currents. In addition to its high output
capability, the LH0020/LH0020C exhibits excel-
lent open loop gain, typically in excess of 100 dB.
The parameters of the LH0020 a:e guarante;d
over the temperature range of -55 C to +125 C
< <and ±5V Vs ±22V, while those of the
LH0020C are guaranteed over the temperature
range of DoC to 85°C and::;:: ±5V ::;:: Vs ::;:: ±18V.
Additional features include:
• Low offset voltage typically 1.0 mV at 25°C
over the entire common mode voltage range.
Schematic and Connection Diagrams
Amplifiers
• Low offset current typically 10 nA at 25°C for
the LH0020 and 30 nA for the LH0020C.
• Offset voltage is adjustable to zero with a single
potentiometer.
• ±14V, 50 mA output capability.
Output current capability, excellent input char·
acteristics, and large open loop gain make the
LH0020/LH0020C suitable for application in a
wide variety of applications from precision dc
power supplies to precision medium power
comparator.
