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 V
P-P
typical) is internally clamped at 1.25 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
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.
