Manufacturer:IR Description:DESCRIPTION LS1240A is a monolithic integrated circuit designed to replace the mechanical bell in telephone sets in connection with an electro-acoustical converter. It can drive directly a piezoceramic converter (buzz- er)or a dynamic loudspeaker. The output current capability of LS1240A is higher than standard ringer. For driving a dynamic loud- speaker LS1240A can simply use a decoupling ca- pacitor, thus eliminating the usual transformer. No current limitation is provided on the output stage of LS1240A, so a minimum load DC of 50 Ω is ad- viced, in series with a proper capacitor. The two tone frequencies generated are switched by an internal oscillator in a fast sequence and made audible across an output amplifier in the loud- speaker, both tone frequencies and the switching frequency can be externally adjusted. |
