The LMH6321MR is a high speed Unity Gain Buffer with adjustable current limit. It slews at 1800V/μs and has a small signal bandwidth of 110MHz while driving a 50R load. It can drive ±300mA 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 to 300mA with a ±5mA ±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.
