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.
