TK15411

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 V_P-P typical) is internally clamped to 1.25 V and amplified 6 dB to produce 2 V_P-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 W of power. Nominal power dissipation (no input) is typically 73 mW.

The TK15411M is available in the SOT23L-8 surface mount package.
