... LM6125/LM6225/LM6325 High Speed Buffer General Description The LM6125 family of high speed unity gain buffers slew at 800 V/µs and have a small signal bandwidth of 50 MHz while ± driving a 50 load. These buffers drive do not oscillate while driving large capacitive loads. The LM6125 contains unique features not found in power buffers; ...
