TA8819F

The TA8819F can be directly driven by battery because it operates on 3.3 to 7.5 V. Effect of fluctuations in supply voltage are minimized.Built-in automatic contrast limiter(ACL) utilizes LCD panel dynamic range, delivering clear image reproduction.Features of TA8819F are: (1)video circuit block: secondary differential sharpness adjustment(DC control); unicolor contrast control; (2)chroma circuit block: 2-axis demodulation primary color output; (3)sync playback circuit block:high-performance sync separation;countdown oscillation fequency adjustment-free; stable vertical sync performance even when synchronization fails.

The absolute maximum ratings of TA8819F can be summerized as:(1)power supply voltage, Vcc is 8 V; (2)input signal voltage, ein is 9 V; (3) power dissipation, PD is 890 mW; (4)operating temperature, Topr is -20 to 75; (5)storage temperature, Tstg is -55 to 150.
