General Description
The CLC3800 (6dB) and CLC3801 (9dB) are triple low cost video amplifiers
capable of driving 2V
pp
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.
The CLC3800 video amplifier offers a fixed gain of 6dB. This integrated
gain compensates for the voltage drop inherent in properly terminated video
loads; ensuring a 1V
pp
video signal is present at the load. If additional gain is
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.
These video amplifiers operate from 3V to 7V supplies and consume 8.8mA of
supply current, making them well suited for battery powered devices.

Absolute Maximum Ratings
The safety of the device is not guaranteed when it is operated above the “Absolute Maximum Ratings”. The device should
not be operated at these “absolute” limits. Adhere to the “Recommended Operating Conditions” for proper device func-
tion. The information contained in the Electrical Characteristics tables and Typical Performance plots reflect the operating
conditions noted on the tables and plots.
