TEA1110A
Datasheet
General description
The TEA1110A is a bipolar integrated circuit that performs all speech and line interface functions required in fully electronic telephone sets. It performs electronic switching between speech and dialling. The IC operates at a line voltage down to 1.6 V DC (with reduced performance) to facilitate the use of telephone sets connected in parallel.
All statements and values refer to all versions unless otherwise specified.
Features
- Low DC line voltage; operates down to 1.6 V (excluding voltage drop over external polarity guard)
- Voltage regulator with adjustable DC voltage
- Provides a supply for external circuits
- Symmetrical high impedance inputs (64 kOhm) for dynamic, magnetic or piezo-electric microphones
- Asymmetrical high impedance input (32 kOhm) for electret microphones
- DTMF input with confidence tone
- MUTE input for pulse or DTMF dialling
- Receiving amplifier for dynamic, magnetic or piezo-electric earpieces
- AGC line loss compensation for microphone and earpiece amplifiers.
