Comlinear® CLC3800, CLC3801
Triple, Standard Definition Video Amplifiers
F E A T U R E S
General Description
nꢀ
Integrated 4th-order, 8MHz filters
The CLC3800 (6dB) and CLC3801 (9dB) are triple low cost video amplifiers

Integrated 6 or 9dB video drivers
8.8mA total supply current
capable of driving 2Vpp into 1 (150Ω), 2 (75Ω), or 3 (50Ω) video loads. The
CLC3800 and CLC3801 feature integrated 8MHz, 4th-order low pass filters
designed to cleanly pass standard definition video signals while filtering out
noise and other unwanted signals , resulting in a crisper, cleaner video signal.
The 4th-order filters provide improved image quality when compared to 2nd-
order passive filtering solutions.

AC or DC coupled outputs
DC-coupled outputs remove the need
for AC-coupling capacitors
The CLC3800 video amplifier offers a fixed gain of 6dB. This integrated
gain compensates for the voltage drop inherent in properly terminated video

Each channel can drive 2Vpp into 1, 2,
or 3 video loads (150Ω, 75Ω or 50Ω)

required, the CLC3801 video amplifier offers a fixed gain of 9dB.

All three video amplifiers can be driven by DC-coupled signals. Their outputs
can drive either AC- or DC-coupled loads.
Operates from 3V to 7V supplies
Pb-free SOIC-8 package
These video amplifiers operate from 3V to 7V supplies and consume 8.8mA of
supply current, making them well suited for battery powered devices.
