National Semiconductor Corp. has introduced a high-speed, 30V buffer amplifier called the LMH6321 suitable for industrial, medical, and test and measurement applications.

According to the company, the unity-gain buffer delivers 300mA of continuous output current and is stable under any capacitive load when driven by a 50-ohm source. It operates with a 30V supply voltage, providing the maximum possible dynamic range at the output. This wide dynamic range is important for applications requiring a large output swing, such as semiconductor automatic test equipment, the company explained.

Other key features of the device include small signal bandwidth of 110MHz while driving a 50-ohm load; continuously adjustable current limit from 10mA to 300mA with ±5mA and ±five per cent accuracy provides extremely fine control of current settings; 1,800V/μs slew rate; thermal shutdown protection to prevent overheating; error flag to signal a fault condition; thermally enhanced TO-263 and PSOP-8 packages to help with heat dissipation; and, guaranteed performance from -40°C to 125°C.

The LMH6321 is already available and priced at Rs.154.73 ($3.43) in 1,000-unit quantities. Pb-free package options are available.
