KKA1062A Datasheet Telephone Speech Network

Manufacturer: KODENSHI (Kodenshi AUK Group)

Overview: .. TECHNICAL DATA TELEPHONE SPEECH NETWORK WITH DIALER INT`ERFACE.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The KKA1062 and KKA1062A are integrated circuits that perform all speech and line interface functions required in fully electronic telephone sets.

They perform electronic switching between dialing and speech.

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

Key Features

  • - Low DC line voltage; operates down to 1.6V (excluding polarity guard) - Voltage regulator with adjustable static resistance - Provides a supply for external circuits - Symmetrical high-impedance inputs (64 kΩ) for dynamic, magnetic or piezo-electric microphones - Asymmetrical high-impedance input (32 kΩ) for electret microphones - DTMF signal input with confidence tone - Mute KKA1062/1062A PIN.
