AN6478FBQ

The AN6478FBQ is designed as one kind of cordless telephone speech network IC incorporating cross-point switch. This device incorporates a cross-point switch controlled by serial input. It allows speech path switching and mixing, and provides for three- or four-person communication and other sophisticated functions.

Features of the AN6478FBQ are:(1)The speech block can operate on line voltage, with no external power supply, and is operational even during a commercial power failure; (2)Incorporates a receiver noise reducing function to improve the handset's howling margin; (3)Incorporates auto. PAD, dial mute, DC voltage regulation, and other basic speech functions; (4)The cross-point switch can be operated independently; (5)Each output of the cross-point switch can correspond to multiple inputs, allowing three- or four-person communication; (6)The REC/PLAY amplifiers incorporate ALC and VOX circuits; (7)Receiver volume can be increased by 6 dB or 9 dB.

The absolute maximum ratings of the AN6478FBQ can be summarized as:(1)Storage temperature:55 to+150 ;(2)Operating ambient temperature: 20 to +75 ;(3)Power dissipation: 640 mW. If you want to know more information about it, please download the datasheet in www.seekic.com or www.chinaicmart.com .
