General Description
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 current 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.
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.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR.
The Long Term Failure Rates were calculated
at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress
temperature of 150°C to an application temperature of 55°C.
