The CLC412 is a high-speed dual wideband video op amp that combines a high-speed complementary bipolar process with National's current-feedback topology. It 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. It also has 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.
