GENERAL DESCRIPTION
The SPT9405 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
terminated cable). The standard video input signal (1 V
internally clamped and amplified 6 dB using internal circuitry
and feedback resistors to produce a 2 V
coupled 150 load. The internal 1.5 k resistor provides gain

compensation for low frequency signals. (See the typical
interface circuit diagram.)
The SPT9405 features a standby mode which draws only
120 W of power. Nominal power dissipation (no input) is
typically 37.5 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.
