Cadeka Microcircuits LLC has introduced the CLC3800 and CLC3801 low-power triple video amplifiers that are designed to meet the requirements of today's cost-sensitive, standard definition (SD) consumer and industrial video applications.

Carrying the Comlinear brand, the amplifiers consume only 26.4mW and offer differential gain/phase (0.05 percent/0.02).

The Comlinear video amplifiers feature integrated 8MHz, fourth-order low pass filters designed to cleanly pass SD video signals while filtering out noise and other unwanted signals, resulting in a crisper, cleaner video signal.

These amplifiers also integrate high-performance, fixed-gain video drivers that use Cadeka's amplifier design expertise. The CLC3800 offers a fixed gain of 6dB. If additional gain is required, the CLC3801 video amplifier offers a fixed gain of 9dB. The two gain options make these amplifiers well suited for a variety of video DACs and encoders.

Each channel of the CLC3800 or CLC3801 can drive two AC- or DC-coupled video loads. This allows today's STB, PVR, LCDTV, portable DVD or video surveillance systems to provide the end user with additional output configurations.
