TEA1118; TEA1118A
Information as of 2000-08-19
TEA1118; TEA1118A; Versatile cordless transmisssion circuit
The TEA1118 and TEA1118A are bipolar integrated circuits that perform all speech and line interface functions required in cordless
telephone base stations. The ICs operate at a line voltage down to 1.6 V DC (with reduced performance) to facilitate the use of telephone
sets connected in parallel.
The TEA1118A offers in addition to the TEA1118 electronic switching between speech and dialling. Moreover the transmit amplifier can be
disabled during speech condition by means of a transmit mute function.
All statements and values refer to all versions unless otherwise specified.
l
Low DC line voltage; operates down to 1.6 V (excluding polarity guard)
l
Voltage regulator with adjustable DC voltage
l
Provides a supply for external circuits
l
Symmetrical high impedance transmit inputs (62.5 k
) with large signals handling capabilities [up to 1 V (RMS value) with less than
2% THD]
l
Receive amplifier for dynamic, magnetic or piezoelectric earpieces
l
AGC line loss compensation for transmit and earpiece amplifiers
l
DTMF input with confidence tone (TEA1118A only)
l
MUTE input for pulse or DTMF dialling (TEA1118A only)
l
Transmit mute function, also enabling the DTMF input (TEA1118A only).
