CLC410
Fast Settling, Video Op Amp with Disable
General Description
The current-feedback CLC410 is a fast settling, wideband,
monolithic op amp with fast disable/enable feature. De-
signed for low gain applications (A
V
=
1 to
8), the
CLC410 consumes only 160mW of power (180mW max) yet
provides a -3dB bandwidth of 200MHz (A
V
= +2) and 0.05%
settling in 12ns (15ns max). Plus, the disable feature pro-
vides fast turn on (100ns) and turn off (200ns). In addition,
the CLC410 offers both high performance and stability with-
out compensation - even at a gain of +1.
The CLC410 provides a simple, high performance solution
for video switching and distribution applications, especially
where analog buses benefit from use of the disable function
to "multiplex" signals onto the bus. Differential gain/phase of
0.01%/0.01 provide high fidelity and the 60mA output cur-
rent offers ample drive capability.
The CLC410's fast settling, low distortion, and high drive
capabilities make it an ideal ADC driver. The low 160mW
quiescent power consumption and very low 40mW disabled
power consumption suggest use where power is critical
and/or "system off" power consumption must be minimized.
The CLC410 is available in several versions to meet a
variety of requirements. A three letter suffix determines the
version.

Note 1: "Absolute Maximum Ratings" are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the devices
should be operated at these limits. The table of "Electrical Characteristics" specifies conditions of device operation.
Note 2: Min/max ratings are based on product characterization and simulation. Individual parameters are tested as noted. Outgoing quality levels are determined
from tested parameters.
Note 3: AJ-level: spec. is 100% tested at +25C, sample at 85C.
Note 4: Noise tests are performed from 5MHz to 200MHz.
