GENERAL DESCRIPTION
The LH0032 is a FET input, high slew rate amplifier capable
of driving up to 100mA current.
With wide bandwidth, high slew rate, high input impedance
and high current drive capability, LH0032 is an ideal choice for
many applications that includes high speed integrator, video
amplifier, summing amplifier, high speed D/A converters, etc.

Note 1.
LH0032G/CG are 100% production tested as specified at 25
o
C, Specifications at temperature extremes are verified by testing, periodic
characterization, or correlation.
Note 2.
Specification is at 25
o
C junction temperature due to requirements of high-speed automatic testing. Actual values at operating
temperature will exceed the value at T
J
= 25
o
C. When supply voltages are
±15V,
no-load operating junction temperature may rise 40-60
o
C above
ambient, and more under load conditions. Accordingly, V
OS
may change one to several mV, and I
B
and I
OS
will change significantly during
warm-up. Refer to I
B
and I
OS
vs. temperature graph for expected values.
Note 3.
Measured in still air 7 minutes after application of power. Guaranteed thru correlated automatic pulse testing.
Note 4.
∆V
OS
/∆T is the average value calculated from measurements at 25
o
C and T
MAX
, specifications at temperature are verified by testing,
periodic characterization, or correlation.
Note 5.
Not 100% production tested; verified by testing, periodic characterization, or correlation.
Note 6.
Guaranteed by CMRR test condition.
Note 7.
