DESCRIPTION

Operating from a single +5 V supply, the TK15405 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 Ω load. The standard video input signal (1 VP-P typical) is internally clamped at 1.25 V and amplified 6 dB to produce 2 VP-P (typical) into a series 75 Ω resistor and 75 Ω cable load. The internal 1.5 k SAG function resistor provides gain compensation for low frequency signals. During standby (Pin 1 grounded), the TK15405 consumes only 120 µW of power. Nominal power dissipation (no input) is typically 38 mW.

The TK15405M is available in the very small SOT23-6 surface mount package.
