CLC412
Dual Wideband Video Op Amp
General Description
The CLC412 combines a high speed complementary bipolar
process with National's current feedback topology to pro-
duce a very high speed dual op amp. The CLC412 provides
a 250MHz small signal bandwidth at a gain of +2V/V and a
1300V/s slew rate while consuming only 50mW per ampli-
fier from
5V supplies.
The CLC412 offers exceptional video performance with its
0.02% and 0.02 differential gain and phase errors for NTSC
and PAL video signals while driving one back terminated
75
load. The CLC412 also offers a flat gain response of
0.1dB to 30MHz and very low channel-to-channel crosstalk
of -76dB at 10MHz. Additionally, each amplifier can deliver a
70mA continuous output current. This level of performance
makes the CLC412 an ideal dual op amp for high density
broadcast quality video systems.
The CLC412's two very well matched amplifiers support a
number of applications such as differential line drivers and
receivers. In addition, the CLC412 is well suited for Sallen
Key active filters in applications such as anti-aliasing filters
for high speed A/D converters. Its small 8-pin SOIC package,
low power requirement, low noise and distortion allow the
CLC412 to serve portable RF applications such as IQ chan-
nels.

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.
