Both amplifiers have a fixed gain of 6 dB and can be used in series for 12 dB gain. The luminance (Y) input is clamped at 1.29 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. The chromanance (C) input is biased at 2.6 V and amplified 6 dB to produce 1.1 VP-P (typical) into a series 75 Ω resistor and 75 Ω cable load. During standby (Pin 3 grounded), the TK15407 consumes only 119 µW of power. Nominal power dissipation (no input) is typically 76 mW. The TK15407 is ideally suited for S-VHS systems. The TK15407M is available in the very small SOT23L-8 surface mount package.
