| Description | L3240 is a monolithic integrated circuit designed to replace the mechanical bell in telephone sets, in connectionwith an electro acoustical converter. The device can drive either directly a piezo cera... |
| Features |
the AC ring signal and the circuit is designed so that noise on the line or variations of the ringing signal cannot affect the correct operation of the devices. The output bridge configuration allows to use a high impedance transducer with acoustical results much better than in a single ended configuration. The two outputs can also be connected independently to different converters or actuators (acoustical, opto, logic).
