Monolithic Linear IC
LA73076V
Video Driver for DVC/DSC,
Cell Phone
Overview
The LA73076V is a low voltage drive (2.7V to 3.6V) video driver developed for portable appliances including digital
video cameras, digital still cameras and cell phones. It incorporates a minus-voltage generator that allows the LA73076V
to generate its output with the pedestal voltage set to 0V, so that no output coupling capacitor is required. This enables
substantial reduction in mounting space without concerned about V-sag.
Features
• Output coupling capacity not required
• Low-voltage drive (VCC = 2.7V to 3.6V)
• Νο V-sag
• Sextic LPF incorporated (fc = 10MHz)
• 6dB amplifier
• Current drain of 0µA in the standby mode
• Output drive capable of covering maximum 75Ω output, one channel

(Note 6)
As the minus power supply in this IC generates the clock for charge pump power supply by extracting the sink component
of the input video signal (synchronous isolation) and by detecting its fall, the portion around the V-syncrhonization of this IC
output may be reduced when the pseudo V signal without cut-in pulse is inserted as in the case of certain analog VCR
special play (search). On the contrary, there is no problem when the pseudo V signal has the cut-in pulse. Pay due attention
on this fact during use.
