LA73076V

Ordering number : ENA0911 Monolithic Linear IC LA73076V Overview Video Driver for DVC/DSC, Cell Phone 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 Specifications Maximum Ratings at Ta = 25°C Parameter Maximum supply voltage Allowable power dissipation Operating temperature Storage temperature Symbol VCC max Pd max Topr Tstg Ta ≤ 80°C, *Mounted on a specified board Conditions Ratings 4.0 220 -20 to +80 -55 to +150 Unit V mW °C °C *: Mounted on a specified board: 114.3mm×76.1mm×1.6mm, glass epoxy Any and all SANYO Semiconductor Co.,Ltd. products described or contained herein are, with regard to "standard application", intended for the use as general electronics equipment (home appliances, AV equipment, communication device, office equipment, industrial equipment etc.).

(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.
