LMH6321

300 mA High Speed Buffer with Adjustable Current Limit

General Description

Features

n High slew rate

1800 V/µs

110 MHz

300 mA

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.

n Wide bandwidth

n Continuous output current

n Output current limit tolerance

n Wide supply voltage range

n Wide temperature range

n Adjustable current limit

n High capacitive load drive

n Thermal shutdown error flag

5 mA 5%

5V to 15V

−40˚C to +125˚C

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

adjusting 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

n Line driver

n Pin driver

n Sonar driver

n Motor control

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

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

tures 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.
