TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA8696F
γ Correction IC for LCD TV
TA8696F
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.
Weight: 0.63 g (typ.)
· 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.
