BA8206是日本ROHM公司生产的多功能电话用音调振铃器集成电路。它可在电话振铃信号到来时自行产生语音振铃声 ,因而可在各种多功能电话、电话应答器以及传真机中直接驱动压电蜂鸣器、变压器式扬声器等负载。文中介绍了BA8206的主要特点、引脚功能和电气参数 ,最后给出了BA8206的典型应用电路和在不同RSL 值时的起始电源压电特性。
BA8206 is a multi-function telephone tone ringer integrated circuit produced by Japan ROHM Corporation. It produces its own voice-activated ringing tone when a telephone ringing signal arrives, enabling the direct actuation of loads such as piezo buzzers and transponder speakers in various multi-function phones, answering machines and fax machines. This paper introduces the main features of the BA8206, pin functions and electrical parameters, and finally gives the BA8206 typical application circuit and at different RSL values of the initial power supply piezoelectric properties.
