Overview
TA8696F TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA8696F γ Correction IC for LCD TV TA8696F operates with a power supply voltage of 3.
3 to 7.
5 V and can be directly driven with a dry battery.
Features · · · · · · Enables high-precision γ correction using logarithmic compression.
γ correction for normally white LCD panel is possible.
Offset/cancel input circuit enables high-quality γ correction without distorting the primary color input signals.
Cut-off voltage and drive voltage can be independently controlled.
Unsusceptible to negative effects of fluctuation of power supply voltage.
Either latch mode or through mode can be selected using the CH display mode switching pin.
