详细描述

UTC TEA1110A 是一种通用电话传输电路，可在电子电话机中提供完整的语音和线路接口功能。该设备可在低至 1.6V DC（性能降低）的线路电压下工作，以实现电话机的并联连接。它还实现了语音和拨号之间的电子切换。

TEA1110A 非常适用于线路供电电话机、无绳电话、传真机和答录机等应用。

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.

The TEA1110A is ideal for applications, such as line powered telephone sets, cordless telephones, fax machines and answering machines.
