DESCRIPTION

Operating from a single +5 V supply, the TK15411 is a single-channel video line driver IC that takes a standard video analog input and provides a buffered analog output for driving a 150 ? load. The standard video input signal (1 VP-P typical) is internally clamped to 1.25 V and amplified 6 dB to produce 2 VP-P (typical) into a series 75 ? resistor and 75 ? cable load. The internal 1.5 k? SAG function resistor provides gain compensation for low frequency signals. The built-in superimpose circuit provides two levels (45 and 140 IRE) of character generation to the video signal. During standby (Pin 5 grounded), the TK15411 consumes only 125 μW of power. Nominal power dissipation (no input) is typically 73 mW.
