General Description

The 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/ s 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 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-channels.

The CLC412 is available in the following versions.
