SGZ07是一种新型集成单频率的发声电路。它不仅用作各种报警器,而且可用于玩具模拟声及车铃、门铃、蜂鸣器、闪光器等。它还可作一般脉冲信号源。性能特点:①用电省,一般电源电压为3V,静态功耗电流小于2.5mA。②外接元件少,仅外接一只适当电容即可产生一定节奏的闪光信号和发声信号。③适用电压范围宽,使用电源在2.4～6V,电路功能正常。④有两个控制端,
SGZ07 is a new integrated single-frequency audible circuit. It is not only used as a variety of alarm, but also for the analog sound of toys and the bell, doorbell, buzzer, flasher and so on. It can also be used as a general pulse signal source. Features: ① electricity province, the general power supply voltage is 3V, the static power consumption current is less than 2.5mA. ② less external components, only an appropriate external capacitor can produce a certain rhythm flash signal and audible signal. ③ wide voltage range, the use of power in the 2.4 ~ 6V, circuit function is normal. ④ There are two control ends,
