TEA1062NG-S16-R Datasheet PDF - UTC

●The UTC TEA1062N/TEA1062AN is a bipolar integrated circuit performing all speech and line interface function, required in the fully electronic telephone sets. It performs electronic switching

●between dialing speech. The circuit is able to operate down to D.C. line voltage of 1.6V (with reduced performance) to facilitate the use of more telephone sets in parallel.

●FEATURES

● Low d.c. line voltage; operates down to 1.6V  (excluding polarity guard).

● Voltage regulator with adjustment static resistance.

● Provides supply with limited current for external circuitry.

● Symmetrical high-impedance inputs (64kΩ) for dynamic, magnetic or piezoelectric microphones.

● Asymmetrical high-impedance inputs (32kΩ) for electrets microphones.

● DTMF signal input with confidence tone.

● Mute input for pulse or DTMF dialing.

● Receivering amplifier for several types of earphones.

● Large amplification setting range on microphone and earpiece amplifiers.

● Line loss compensation facility, line current depedant  (microphone and earpiece amplifiers).

● Gain control adaptable to exchange supply.

● Possibility to adjust the d.c. line voltage
