300 mA High Speed Buffer with Adjustable Current Limit
LMH6321 www.ti.com SNOSAL8C –APRIL 2006–REVISED MARCH 2013 LMH6321 300 mA High Speed Buffer with Adjustable Current Limit Check for Samples: LMH6321 1FEATURES DESCRIPTION The LMH6321 is a high speed unity gain buffer that 2• High Slew Rate 1800 V/μs slews at 1800 V/µs and has a small signal bandwidth • Wide Bandwidth 110 MHz of 110 MHz while driving a 50Ω load. It can drive • Continuous Output Current ±300 mA ±300 mA continuously and will not oscillate while driving large capacitive loads. • Output Current Limit Tolerance ±5 mA ±5% • Wide Supply Voltage Range 5V to ±15V The LMH6321 features an adjustable current limit. The current limit is continuously adjustable from 10 • Wide Temperature Range−40°C to +125°C mA to 300 ma with a ±5 mA ±5% accuracy. The • Adjustable Current Limit current limit is set by adjusting an external reference • High Capacitive Load Drive current with a resistor. The current can be easily and instantly adjusted, as needed by connecting the • Thermal Shutdown Error Flag resistor to a DAC to form the reference current. The sourcing and sinking currents share the same current APPLICATIONS limit. • Line Driver The LMH6321 is available in a space saving 8-pin SO • Pin Driver PowerPAD or a 7-pin DDPAK power package. The • Sonar Driver SO PowerPAD package features an exposed pad on the bottom of the package to increase its heat sinking • Motor Control 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.
