Overview

LINEAR INTEGRATED CIRCUIT PROGRAMMABLE TELEPHONE SPEECH CIRCUIT The LS288 is a monolithic integrated circuit in 16 lead dual in-line plastic signed as a repla- cement for the hybrid circuit in telephone sets it performs all the func carried out by this circuit.
With the LS288 it is possible to select the operating mode (fixed or both piezoceramic and dynamic transducers and therefore its sending and receiving paths, can be preset by means of two external resistors.
This fe obtained in AGC operating mode, when the device automatically adjusts the Rx/Tx gai nsate for the line attenuation by sensing the line current.
The LS288 can supply the decoupling FET when g with an electre...
