TEA1062AN
Overview
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.
- 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
