TK15409

Operating from a single +5 V supply, the TK15409 is a video line driver IC that takes standard Y and C analog inputs and provides a composite analog output for driving 150 loads (75 resistor and 75 cable load). Internal summing of the Y and C inputs is performed to produce the composite video output. The luminance (Y) input is clamped at 1.25 V and amplified 6 dB; the chromanance (C) input is biased at 2.0 V and amplified 6 dB. The internal 1.5 k SAG function resistor provides gain compensation for low frequency signals. During standby (Pin 5 grounded), the TK15409 consumes only 127 W of power. Nominal power dissipation (no input) is typically 90 mW.

The TK15409M is available in the very small SOT23L-8 surface mount package.
