GENERAL DESCRIPTION
The SPT9404 is a single video line driver chip that takes a
standard video signal as an analog input and provides a
buffered analog output for driving a 150
Ω
load (75
Ω
back-
terminated cable). The standard video input signal (1 V
P-P
) is
typically amplified 6 dB using external components to pro-
duce a 2 V
P-P
into an AC-coupled 150
Ω
load. (See the typical
interface circuit diagram.)
The SPT9404 features a standby mode which draws only
96
µW
of power. Nominal power dissipation (no input) is
typically 32 mW. It requires a single +5 V supply, operates
over the commercial temperature range (0 to +70
°C)
and is
available in a tiny surface mount (2.9 x 1.6 mm) 6-lead SOT-
23 package.
