TEA1118 Datasheet (NXP) - Versatile cordless transmisssion

TEA1118, Versatile cordless transmisssion

The TEA1118 and TEA1118A are bipolar integrated circuits that perform all speech and line interface functions required in cordless telephone base stations.

The ICs operate at a line voltage down to 1.6 V DC (with reduced performance) to facilitate the use of telephone sets connected in parallel.

The

TEA1118 Features
