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 backterminated cable). The standard video input signal (1 V
typically amplified 6 dB using external components to produce a 2 V
interface circuit diagram.)
into an AC-coupled 150 Ω load. (See the typical
P-P

APPLICATIONS
• Digital Video Disk
• Video Line Driver for Encoders
• Digital Video Tape Recorders
• Video Cassette Recorders
• PC Multimedia
• Consumer Video
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 SOT23 package.
