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 50load. 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.
