BL1062A1 Datasheet Low Voltage Transmission

Manufacturer: SHANGHAI BELLING

Overview: .. BL1062A1 Low voltage transmission circuits with dialer interface 1.

Datasheet Details

The BL1062A1 is integrated circuits that perform all speech and line interface functions required in fully electronic telephone sets.

It performs electronic switching between dialling and speech.

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

Low DC line voltage; operates down to 1.6 V (excluding polarity guard) Voltage regulator with adjustable static resistance Provides a supply for external circuits Symmetrical high-impedance inputs (64 Κ Ω ) for dynamic, magnetic or piezoelectric microphones Asymmetrical high-impedance input (32 ΚΩ) for electret microphones DTMF signal input with confidence tone Mute input for pulse or DTMF dialling, active LOW (MUTE) Receiving amplifier for dynamic, magnetic or piezoelectric earpieces Large gain.
