NSC LH0004 Lh0004 high voltage operational amplifier Datasheet

LH0004 High Voltage Operational Amplifier
General Description
The LH0004 is a general purpose operational amplifier designed to operate from supply voltages up to g 40V. The
device dissipates extremely low quiescent power, typically 8
mW at 25§ C and VS e g 40V.
The LH0004’s high gain and wide range of operating voltages make it ideal for applications requiring large output
swing and low power dissipation.
The LH0004 is specified for operation over the b55§ C to
a 125§ C military temperature range. The LH0004C is specified 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 negative supply; however, the standby current will be increased. 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.
