LS (Wing Shing) – Electronic Two-tone Ringer

For driving a dynamic loud- speaker LSA can simply use a decoupling ca- pacitor, thus eliminating the usual transformer. We are not responsible for any accidents, delays or other issues caused by the forwarder. Storage and Junction Temperature. If the items are defective, please notify us within 3 days of delivery. Short Circuit Current pins 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.
