Integrated Circuit Chip SAA3004T - NXP Semiconductors - Remote control transmitter



Detailed Product Description

Quick Detail:


Remote control transmitter





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.





• Flashed or modulated transmission

• 7 sub-system addresses

• Up to 64 commands per sub-system address

• High-current remote output at VDD = 6 V (−IOH = 40 mA)

• Very low stand−by current (< 2 µA)

• Operational current < 2 mA at 6 V supply

• Wide supply voltage range (4 to 11 V)

• Ceramic resonator controlled frequency (typ. 450 kHz)

• Encapsulation: 20-lead plastic DIL or 20-lead plastic mini-pack (SO-20)
