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. Y Y Y Low input offset voltage typically 0.3 mV Frequency compensation with 2 small capacitors Low power consumption 8 mW at g 40V Applications Y Y Y Y High voltage power supply Resolver excitation Wideband high voltage amplifier Transducer power supply Features Y Y Capable of operation over the range of g 5V to g 40V Large output voltage typically g 35V for the LH0004 and g 33V for the LH0004C into a 2 kX load with g 40V supplies 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.
