Description
The UTC TEA1110A is a versatile telephone transmission circuit providing full speech and line interface functions in electronic telephone sets. This device works at a line voltage which can be as low as 1.6V DC (with reduced performance) to enable parallel^connection of telephone sets. It also realizes electronic switching between speeches and dialling.
full speech and line interface functions in electronic telephone sets. This device works at a line voltage which can be as low as 1.6V DC (with reduced performance) to enable parallel connection of telephone sets. It also realizes electronic switching between speeches and dialling.
The TEA1110A is ideal for applications, such as line powered telephone sets, cordless telephones, fax machines and answering machines.
