YD5104
8.2W BTL AUDIO POWER AMPLIFIER-YD5104
DESCRIPTION
YD5104 is an audio power IC with built-in two channels developed for portable radio cassette tape recorder..
Because of the parts reduction and SIP (Single In line Package), space merit is remarkable. Thermal shut down
protection circuit is built in.
