MC34118 Overview
As a voice switched speaker-phone integrated circuit, the UTC MC34118 includes the necessary amplifiers, attenuators, level detectors and control algorithm. To form the UTC MC34118’s internal circuit, there is an internal microphone amplifier with adjustable gain and mute control, internal transmit and Receive attenuators (operate in a plementary manner), level detectors at both input and output of both attenuators,...
MC34118 Key Features
- Attenuator gain range: 52dB (between Transmit and Receive)
- For line-powered
MC34118 Applications
- For improved sensitivity :4-point signal sensing
- For Transmit and Receive paths: background noise monitors
