ALC3261 Overview
Description
The ALC3261 is a low power, dual I2S interface, 4 channels DAC and 2 channel ADC Audio Codec with a optimized Voice DSP integrated. The primary I2S interface connects to system host chip and its secondary I2S interface can perform as input or output device connected to external processor, blue tooth device or wireless transceiver.
Key Features
- an extra low power cap-free headphone amplifier
- It consumes only less than 10mW power during playback, providing tablet system longer battery life under headphone listening mode
- The DRC in ALC3261 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
- ALC3261 embedded a low power wideband voi
