■ Very Small Output Capacitor Using SAG Function Pin
■ Very Small Package (SOT23L-8)
■ Single +5 V Power Supply Operation
DESCRIPTION
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 Ω loads (75 Ω resistor and 75 Ω 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 kΩ SAG function resistor provides gain compensation
for low frequency signals. During standby (Pin 5 grounded),
the TK15409 consumes only 127 µW of power. Nominal
power dissipation (no input) is typically 90 mW.
The TK15409M is available in the very small SOT23L-8
surface mount package.
