The Contek LS1240A is a monolithic integrated circuit, designed to be as a telephone ringer . It can drive directly a piezo-ceramic converter (buzzer). The output current capacitity of Contek LS1240A is higher than Contek LS1240, For driving a dynamic loudspeaker , Contek LS1240A needs only a decoupling capacitor. |
