16Bit 91dB Audio CODEC with headphone drivers and PWM Controller, SMIC0.18um

Overview

AR34S3E is a mass-production proven sigma-delta mono CODEC designed for portable device applications. It contains PWM (pulse-width-modulated) controller that allows users to configure class-D amplifiers to drive speakers efficiently.
The CODEC contains built-in digital audio interface, along with I2C/MCU/SPI digital controlling interface for on-chip programming.

The IP is available in SMIC 0.18um process.
