LM6125/LM6225/LM6325
High Speed Buffer
General Description
The LM6125 family of high speed unity gain buffers slew at
800 V/碌s and have a small signal bandwidth of 50 MHz while
driving a 50鈩?load. These buffers drive
鹵
300 mA peak and
do not oscillate while driving large capacitive loads. The
LM6125 contains unique features not found in power buffers;
these include current limit, thermal shutdown, electronic
shutdown, and an error flag that warns of fault conditions.
These buffers are built with National鈥檚 VIP
鈩?/div>
(Vertically Inte-
grated 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 di-
electric isolation.
