LH0002 Buffer

General Description

The LH0002 is a general purpose buffer. Its features make it

ideal to integrate with operational amplifiers inside a closed

loop configuration to increase current output. The symmetri-

cal output portion of the circuit also provides a low output

impedance for both the positive and negative slopes of out-

put pulses.

The LH0002 is available in an 8-lead TO-99 can. The

LH0002C is available in an 8-lead TO-99, and a 10-pin

molded dual-in-line package.

The LH0002 is specified for operation over the b55§Cto

125§C military temperature range. The LH0002C is speci-

fied for operation over the 0§Ctoa

85§C temperature range.

Features

YHigh input impedance 400 kX

Note 1: Specification applies for TAe25§C with a12V on Pins 1 and 2; b12V on Pins 6 and 7 for the metal can package and a12V on Pins 1 and 2; b12V 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 0§Ctoa

85§C,

while parameters for the LH0002 are guaranteed over the temperature range b55§Ctoa

125§C unless otherwise specified.

Note 2: Refer to RETS0002X for LH0002 military specifications.

Note 3: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is

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 4: The maximum power dissipation is a function of maximum junction temperature (TJMax), total thermal resistance (iJA), and ambient temperature (TA). The

maximum allowable power dissipation at any ambient is PDe(TJMax bTA)/iJA.

Note 5: For operating at elevated temperatures, the device must be derated based on the thermal resistance iJA and TJMax. TJeTAaPDiJA.

Note 6: Human body model, 1.5 kXin series with 100 pF.
