GENERAL DESCRIPTION
The CLM4122 family are low power, high speed unity gain
buffers that slew at 2000V/
s, having a small signal
bandwidth of 180MHz, delivers 60mA, yet draws only 800
A
supply current.
The 4mW power consumption, fast slew rate, wide bandwidth,
and high output drive make the CLM4122 family the ideal
choice for battery operated equipment.
These same characteristics are the excellent choices for
driving coaxial and switched pair cables.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifications do not
apply when operating the device beyond its rated operating conditions.
Note 2: Slew rate is measured with 50
source impedance at 25
o
C with input DC offset to 2.5V. For accurate measurements, the input slew rate
should be at least 5000V/
s.
Note 3: The test circuit consists of the human body model of 120pF in series with 1500
.
Note 4: The maximum power dissipation is a function of T
J(max),
JA
and T
A
. The maximum allowable power dissipation at any ambient
temperature is P
D
= (T
J(max)
- T
A
)/
JA
.
Note 5: Limits are guaranteed by testing, correlation or periodic characterization.
Note 6: For M & N package,
JA
is measured by soldering the unit directly on a printed circuit board and V
-
pins are connected to 2 square
inches of 2 oz copper.
