Up to 105 dB of SNR, 24-bit stereo CODEC with PDM to PWM transmodulator DAC and embedded regulator
You are here:
16-24Bit 100dB Voice/Audio CODEC in SMIC 40nm LL
The AR82S021 is a silicon proven low-power high-performance voice/audio CODEC IP. The IP features stereo ADC with line-in inputs and stereo DAC with lineout. Built-in programmable gain adjustment provides easy volume control for both recording and playback modes. On-chip regulators yields better PSRR and noise rejection performance suitable for seamless SOC integration where high frequency activities and hence significant ground/substrate noise exists.
It is silicon-proven in SMIC40nmll logic process. The IP is now portable to other logic process node for silicon realization.
