GENERAL DESCRIPTION
The LH0002 is a high speed unity gain buffer designed to
provide high current drive capability at frequencies from DC to
over 50MHz. It is capable of providing a continuous current of
±100mA and a peak of ±400mA. It is ideal to integrate with an
operational amplifier inside a close loop configuration.

Note 1. Specification applies for T A = 25oC with +12V on Pins 1 and 2; -12V on Pins 6 and 7 for the metal can package and +12V on Pins 1 and
2; -12V on Pins 4 and 5 for the dual-in-line package, unless otherwise specified. The parameter guarantees for LH0002C apply over the
temperature range of 0oC to +85 oC while parameters for the LH0002 are guaranteed over the temperature range -55oC to +125oC unless
otherwise specified.
Note 2. Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the devices intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions,
see the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed.
Note 3. The maximum power dissipation is a function of maximum junction temperature (TJMax), total thermal resistance (θJA), and ambient
temperature (TA) maximum allowed power dissipation at any ambient is PD = (TJMax - TA)/θJA.
Note 4. For operating at elevated temperatures, the device must be derated based on the thermal resistance θJA and TJMax. TJ = T A + PDθJA.
Note 5. Human body model, 1.5kΩ in series with 100pF.
