KKA1062/1062A
FEATURES
PIN CONNECTION
- 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
- KKA1062: active HIGH (MUTE)
- KKA1062A: 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

The KKA1062 and KKA1062A 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 KKA1062 (KKA1062A) is packaged in a standard
16-pin plastic DIP and special plastic DIP with internal heatsink is also available.
