BL1110A - Low voltage versatile transmission IC

Description

BL1110A(BL1001) is a low voltage versatile transmission IC.

It offers the entire microphone, receive and line interface functions required in telephone sets.

It performs the interface between the line and the transducers of the handset.

Features

  • Low DC line voltage: operates down to 1.6 V.
  • Voltage regulator with adjustable DC voltage.
  • Provides a supply for external circuits.
  • Symmetrical high impedance inputs (64 kW) for dynamic, magnetic or piezo- electric microphones.
  • Asymmetrical high impedance input (32 kW) for electrets microphones.
  • DTMF input with confidence tone.
  • MUTE input for pulse or DTMF dialing.
  • Receiving amplifier for dynamic, magnetic or piezo-electric.

DESCRIPTION: BL1110A BL1110A(BL1001) is a low voltage versatile transmission IC. It offers the entire microphone, receive and line interface functions required in telephone sets. It performs the interface between the line and the transducers of the handset. It includes a DTMF amplifier, a microphone amplifier and a receive amplifier. The selection between the microphone amplifier and the DTMF amplifier is made with a “MUTE” function. The MUTE/input switches-off both the microphone and the receive amplifiers and switches-on the DTMF amplifier. FEATURES • Low DC line voltage: operates down to 1.
