Published:2011/7/20 8:15:00 Author:Christina | Keyword: infrared, remote control, launch circuit | From:SeekIC

Features The little external components.The wide external power supply voltage range, the value is 4-11V.The SAA3004P uses the 20-pin dual-row DIP plastic package, the SAA3004T uses the 20-pin small size plastic package.The matching model are TDA3048, SAA3009 and SAA3049. Function description The oscillating circuit has the external ceramic filter. The typical value of the reference frequency is 450kHz.When the VDD=6V, the remote control output current is the maximum.In the non-operating state, the power supply current is very small, the value is lower than 2uA; in the operating state, the power supply current is lower than 2mA.It has seven groups of subsystem addresses, every subsystem has 64 instructions.
