TA8751AN

The TA8751AN possesses functions that optimize the CRT drive conditions in televisions, and is an IC that automates the previously complex cutoff adjustment and drive adjustment non-adjustment.It has an RGB TEXT input pin, so TV signal and TEXT signal can be switched between rapidly.The TV's primary colors are DC coupled, so brightness control from previous stages can be utilized.

The absolute maximum ratings of TA8751AN can be summerized as:(1)power supply voltage, Vcc is 15 V; (2)input signal voltage, ein is 5 V; (3)primary color output current, Iout is 3.5 mA; (4)TV/TEXT switching voltage, V12 is -0.5 V to 7.0 V; (5)blanking pulse input voltage, V18 is 5 V to 10 V; (6)adjustment pin voltage, Vcont is 0 to Vcc V; (7)dissipation power, PD is 1.6 W; (8)operating temperature, Topr is -20 to 65; (9)storage temperature, Tstg is -55 to 150.

The electrical characteristics of TA8751AN can be summerized as:(1): power supply current, Icc is 50 mA min, 65 mA typ and 85 mA max when Vcc is 12 V; (2): TV input dynamic range, VTV is 5.0 Vp-p min and 7.0 Vp-p typ; (3): maximum gain, Gm is 1.0 db min, 3.0 dB typ and 5.0 dB max; (4): gain variable width, Gr is 10 dB min, 12 dB typ and 13 dB max; (5): cutoff control variable range is 1.5 V min and 2.0 V typ; (6): horizontal blanking detection level,VHBLK is 1.5 V min, 1.7 V typ and 1.9 V max.
