Semiconductor Power LED Driver IC Circuit High Speed Buffer LM6321M

Quick Detail:

High Speed Buffer

Description:

These high speed unity gain buffers slew at 800 V/µs and have a small signal bandwidth of 50 MHz while driving a 50Ω load. They can drive ±300 mA peak and do not oscillate while driving large capacitive loads. The LM6121 family are monolithic ICs which offer performance similar to the LH0002 with the additional features of current limit and thermal shutdown.

These buffers are built with National’s VIP™ (Vertically Integrated PNP) process which provides fast PNP transistors that are true complements to the already fast NPN devices.

This advanced junction-isolated process delivers high speed performance without the need for complex and expensive dielectric isolation.
