Product specification
TEA1065
FEATURES
• Current and voltage regulator mode with adjustable
static resistances
• Provides supply for external circuitry
• Symmetrical high-impedance inputs for piezoelectric
microphone
• Asymmetrical high-impedance input for electret
microphone
• DTMF signal input with confidence tone
• Mute input for pulse or DTMF dialling
• Power-down input for pulse dial or register recall
• Digital pulse input to drive an external switch transistor
• Receiving amplifier for magnetic, dynamic or
piezoelectric earpieces
• Large gain setting range on microphone and earpiece
amplifiers
• Line loss compensation facility, line current dependent
(on microphone and earpiece amplifiers)
• Adjustable gain control
• DC line voltage adjustment facility
GENERAL DESCRIPTION
The TEA1065 is a bipolar integrated circuit which performs
all speech and line interface functions that are required in
fully electronic telephone sets with adjustable DC mask.
The circuit performs electronic switching between dialling
and speech internally.
