Versatile cordless transmisssion circuit
Product specification
TEA1118; TEA1118A
FEATURES
Low DC line voltage; operates down to 1.6 V (excluding
polarity guard)
Voltage regulator with adjustable DC voltage
Provides a supply for external circuits
Symmetrical high impedance transmit inputs (62.5 k)
with large signals handling capabilities [up to
1 V (RMS value) with less than 2% THD]
Receive amplifier for dynamic, magnetic or
piezoelectric earpieces
AGC line loss compensation for transmit and earpiece
amplifiers
DTMF input with confidence tone (TEA1118A only)
MUTE input for pulse or DTMF dialling (TEA1118A only)
Transmit mute function, also enabling the DTMF input
(TEA1118A only).
GENERAL DESCRIPTION
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.
APPLICATIONS
Cordless telephone base stations
Fax machines
Answering machines.
QUICK REFERENCE DATA
Iline = 15 mA; VEE = 0 V; RSLPE = 20 ; AGC pin connected to VEE; Zline = 600 ; f = 1 kHz; Tamb = 25 °C;
unless otherwise specified.
