U4082B Overview
As a voice switched speaker-phone integrated circuit, the UTC U4082B includes the necessary amplifiers, attenuators, level detectors and control algorithm. To form the UTC U4082B’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,...
U4082B Key Features
- Attenuator gain range: 52dB (between Transmit and Receive)
- For line-powered
U4082B Applications
- For improved sensitivity :4-point signal sensing
- For Transmit and Receive paths: background noise monitors
