GENERAL DESCRIPTION

The SPT9402 is a triple video line driver chip that takes

standard video signals as analog inputs and provides buff-

ered analog outputs for driving 150 Ω loads (75 Ω back-

terminated cables). The standard video input signals (1 VP-P)

are typically amplified 6 dB using external components to

produce a 2 VP-P into an AC-coupled 150 Ω load. (See the

typical interface circuit diagram.)

The SPT9402 features a standby mode which draws only

113 µW of power. Nominal power dissipation (no input) is

typically 95 mW. It requires a single +5 V supply, operates

over the commercial temperature range (0 to +70 °C) and is

available in a very small (5.0 x 4.4 mm) 12-lead Shrink Small

Outline Package (SSOP).
