GENERAL DESCRIPTION
The CLM4122 family are low power, high speed unity gain
buffers that slew at 2000V/µs, having a small signal
bandwidth of 180MHz, delivers 60mA, yet draws only 800µA
supply current .
The 4mW power consumpt ion, fast slew rate, w ide bandwidth,
and high output drive make the CLM4122 family the ideal
choic e fo r battery operated eq u ip m en t .
These same characteristics are the excellent choices for
driving coaxial and switched pair ca bles.
