The Everest Semiconductor ES8311 is a low-power, high-performance audio codec IC featuring multibit delta-sigma analog-to-digital conversion (ADC) and digital-to-analog conversion (DAC). It is designed for audio recording and playback applications that require clear sound quality, low power consumption, and a compact circuit design.

The ES8311 supports 24-bit audio processing with sampling rates ranging from 8 kHz to 96 kHz. It provides I2S/PCM digital audio interfaces and an I2C control interface, allowing integration with microcontrollers, processors, and embedded audio systems.

This audio codec includes features such as a low-noise preamplifier, noise-reduction filters, automatic level control (ALC), a noise gate, dynamic range compression, and pop-and-click noise suppression. It supports both analog and digital microphones and offers headphone-driving capability for versatile audio system designs.

Operating from a 1.8V to 3.3V supply, the ES8311 is housed in a compact QFN-20-EP package measuring 3 × 3 mm, making it suitable for space-constrained and battery-powered electronic devices.
