LH0004 High Voltage Operational Amplifier
General Description
The LH0004 is a general purpose operational amplifier de-
signed to operate from supply voltages up to
 g
40V. The
device dissipates extremely low quiescent power, typically 8
mW at 25
§
C and V
S
e
 g
40V.
The LH0004’s high gain and wide range of operating volt-
ages make it ideal for applications requiring large output
swing and low power dissipation.
The LH0004 is specified for operation over the
 b
55
§
C to
a
125
§
C military temperature range. The LH0004C is speci-
fied for operation over the 0
§
C to
a
85
§
C temperature range.

Schematic and Connection Diagrams
TL/H/5559–2
Note:
 Pin 7 must be grounded or connected to a
voltage at least 5V more negative than the positive
supply (Pin 9). Pin 7 may be connected to the nega-
tive supply; however, the standby current will be in-
creased. A resistor may be inserted in series with
Pin 7 to Pin 9. The value of the resistor should be a
maximum of 100 k
X
 per volt of potential between
Pin 3 and Pin 9.
