GENERAL DESCRIPTION
The CLM4121 family are high speed unity gain buffers that
slew at 2000V/
μ
s, having a small signal bandwidth of
180MHz, delivers 150mA, yet draws only 7mA supply current.
The fast slew rate, wide bandwidth, and high output drive
make the CLM4121 family the ideal choice for closed loop
buffer applications with wide band op amps.
These same characteristics are the excellent choices for open
loop applications such as driving coaxial and switched pair
cables.
