LH0005/LH0005A Operational Amplifier
General Description
The LH0005/LH0005A is a hybrid integrated cir-
cuit operational amplifier employing thick film
resistors and discrete silicon semiconductors in its
design_ The select matching of the input pairs of
transistors results in low input bias currents and a
very low input offset current, both of which ex-
hibit excellent temperature tracking. In addition,
the device features:
• Very high output current capability: ±50 mA
into a 100 ohm load
• Low standby power dissipation: typically
60 mW at ±12V
• High input resistance: typically 2M at 25°C

• Full operating range: -55°C.to +125°C
• Good high frequency response: unity gain at
30 MHz
With no external roll-off network, the amplifier is
stable with a feedback ratio of 10 or greater. By
adding a 200 pF capacitor between pins 9 and 10, .
and a 200 ohm resistor in series with a 75 pF
capacitor from pin 4 to ground, the amplifier is
stable to unity gain. The unity gain loop phase
margin with the above compensation is typically
70 degrees. With a gain of 10 and no compensation
the loop phase margin is typically 50 degrees.
