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鈥檚 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 鈥?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 kX per volt of potential between
Pin 3 and Pin 9
