GENERAL DESCRIPTION
The SPT9406 is a single video line driver chip that takes a
standard video chroma signal as an analog input and pro-
vides 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 biased and amplified 6 dB using internal
circuitry and feedback resistors to produce a 2 VP-P into an
AC-coupled 150 Ω load. (See the typical interface circuit
diagram.)
The SPT9406 features a standby mode which draws only
120 µW of power. Nominal power dissipation (no input) is
typically 41 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.
