NXP Semiconductors TEA1118
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 TEA1118A offers in addition to the TEA1118 electronic switching between speech and dialling.| Part No. | TEA1118 |
