DESCRIPTION
Operating from a single +5 V supply, the TK15408 is a dual
video driver IC that takes standard video signals as analog
inputs and provides buffered analog outputs for driving
150
Ω
loads (series 75
Ω
resistor and 75
Ω
cable load).
Both amplifiers have a fixed gain of 6 dB with internal
clamping circuits. Each input is clamped at 1.29 V and
amplified 6 dB to produce 2 V
P-P
(typical) into a series
75
Ω
resistor and 75
Ω
cable load. The internal 1.5 k SAG
function resistors provide gain compensation for low
frequency signals. Nominal power dissipation (no input) is
typically 76 mW. The TK15408 is ideally suited for S-VHS
systems.
The TK15408M is available in the very small SOT23L-8
surface mount package.
