CLC412
Dual Wideband Video Op Amp
General DescriptionThe CLC412 combines a high-speed complementary bipolar process
with National's current-feedback topology to produce a very high-
speed dual op amp. The CLC412 provides a 250MHz small-signal
bandwidth at a gain of +2V/V and a 1300V/μs slew rate while
consuming only 50mW per amplifier 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 75Ω 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-channels.
The CLC412 is available in the following versions.
