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 Ω load (75 Ω back-

terminated cable). The standard video input signal (1 VP-P) is

internally clamped and amplified 6 dB using internal circuitry

and feedback resistors to produce a 2 VP-P into an AC-

coupled 150 Ω load. The internal 1.5 kΩ resistor provides gain

compensation for low frequency signals. (See the typical

interface circuit diagram.)

The SPT9405 features a standby mode which draws only

120 µW 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.
