Product specification
Remote control transmitter
SAA3004
GENERAL DESCRIPTION
The SAA3004 transmitter IC is designed for infrared remote control systems. It has a total of 448 commands which are
divided into 7 sub-system groups with 64 commands each. The sub-system code may be selected by a press button,
a slider switch or hard wired.
The SAA3004 generates the pattern for driving the output stage. These patterns are pulse distance coded. The pulses
are infrared flashes or modulated. The transmission mode is defined in conjunction with the sub-system address.
Modulated pulses allow receivers with narrow-band preamplifiers for improved noise rejection to be used. Flashed pulses
require a wide-band preamplifier within the receiver.
The SAA3004 has the following features:
Flashed or modulated transmission
7 sub-system addresses
Up to 64 commands per sub-system address
High-current remote output at V
