Triple,
Standard Definition Video Amplifiers
General Description
The CLC3800 (6dB), CLC3801 (9dB), and CLC3802 (12dB) are triple low cost
video amplifiers capable of driving 2V
pp
into 1 (150Ω) or 2 (75Ω) video loads.
The CLC3800, CLC3801, and CLC3802 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 and the
CLC3802 offers 12dB.
All three video amplifiers can be driven by DC-coupled signals. Thier 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.
