LMH6321

300 mA High Speed Buffer with Adjustable Current Limit

General Description

Features

The LMH6321 is a high speed unity gain buffer that slews at

1800 V/µs and has a small signal bandwidth of 110 MHz while

driving a 50Ω load. It can drive ±300 mA continuously and will

not oscillate while driving large capacitive loads.

The LMH6321 features an adjustable current limit. The cur-

rent limit is continuously adjustable from 10 mA to 300 ma

with a ±5 mA ±5% accuracy. The current limit is set by ad-

justing an external reference current with a resistor. The

current can be easily and instantly adjusted, as needed by

connecting the resistor to a DAC to form the reference current.

The sourcing and sinking currents share the same current

limit.

Applications

The LMH6321 is available in a space saving 8-pin PSOP or

a 7-pin TO-263 power package. The PSOP package features

an exposed pad on the bottom of the package to increase its

heat sinking capability. The LMH6321 can be used within the

feedback loop of an operational amplifier to boost the current

output or as a stand alone buffer.
