ILA1062/ILA1062A
TELEPHONE SPEECH NETWORK WITH DIALER INTERFACE
DESCRIPTION
The ILA1062 and ILA1062A are integrated circuits that perform all speech and line interface
functions required in fully
electronic telephone sets. They perform electronic switching between dialing and speech. The ICs
operates at line voltage down
to 1.6 V DC (with reduced performance) to facilitate the use of more telephone sets connected in
parallel.
All statements and values refer to all versions unless otherwise specified. The ILA1062(ILA1062A)
is packaged in a standard
16-pin plastic DIP and special plastic DIP with internal heatsink is also available.
FEATURES
· Low DC line voltage; operates down to 1.6V
(excluding
polarity guard)
· Voltage regulator with adjustable static resistance
· Provides a supply for external circuits
· Symmetrical high-impedance inputs (64 kΩ) for
dynamic, magnetic or piezo-electric microphones
· Asymmetrical high-impedance input (32 kΩ) for
electret
microphones
· DTMF signal input with confidence tone
· Mute input for pulse or DTMF dialing
- ILA1062: active HIGH (MUTE)
- ILA1062A: active LOW (MUTE)
· Receiving amplifier for dynamic, magnetic or
piezo-electric earpieces
· Large gain setting range on microphone and
earpiece
amplifiers
· Line loss compensation (line current dependent) for
microphone and earpiece amplifiers
· Gain control curve adaptable to exchange supply
· DC line voltage adjustment facility
