GENERAL DESCRIPTION
The CLM4121 family are high speed unity gain buffers that
slew at 2000V/µs, having a small signal bandwidth of
180MHz, del ivers 150m A, yet dr aws on ly 7mA supply curren t.
The fast slew rate, wide bandwidth, and high output drive
make the CLM4121 family the ideal choice for closed loop
buffer appl ications with wide band op amps.
These same characteristics are the excellent choices for ope n
loop applications such as driving coaxial and switched pair
cables.
