ALC5670 Overview
Description
The ALC5670 is a high performance, low power, up to three I2S interface audio CODEC with embedded low power/high performance Voice DSP. Three I2S interface can connect to different devices and let the ALC5670 to be an Audio Hub.
Key Features
- an ultra low power cap-free headphone amplifier
- It consumes only less than 5mW power during playback, providing mobile system longer battery life under headphone listening mode
- The multi-section DRC in ALC5670 continuously monitors the DAC output level
- When the power level is low, it increases the input signal gain to make it sound louder
- At the same time, if a peaking signal is detected, it autonomously reduces the applied gain to avoid hard clipping
- It ensures the maximum/consistent signal amplitude without producing audio clipping and speaker damage
- For microphone recording, the DRC in ALC5670 can be used as AGC(Auto Gain Controller) to maintain a constant recording volume
- Besides, a dynamic
