ES8311 low power mono audio I2S codec WQFN-20

Description

ES8311 low power mono audio I2S codec WQFN-20

Product Description

The ES8311 is a low-power, single-channel (mono) audio codec IC combining ADC and DAC functions. It supports I²S/PCM audio interfaces, has a differential output stage (or headphone driver), and includes analog input capabilities. It is well-suited for embedded audio devices (e.g. voice output, small speaker systems) requiring a compact codec with moderate audio quality and low power consumption.

Key Features

• Codec type: Mono audio codec (ADC + DAC)

• Audio resolution: 24-bit for both ADC and DAC paths

• Supported sampling rates: 8 kHz up to 96 kHz

• Signal-to-noise ratio (SNR):
    • DAC: ~110 dB (typical) 
    • ADC: ~100 dB (typical)

• Total harmonic distortion + noise (THD+N):
    • DAC: around –80 dB 
    • ADC: around –93 dB

• Differential analog outputs (OUTP / OUTN) or single-ended use via coupling capacitors, with headphone driver support

• Analog input channel(s) with differential option for microphone or line input

• Supported serial audio data formats: I²S, left-justified, MSB-first, PCM modes

• Master or Slave mode for digital clocks (MCLK, SCLK, LRCK)

• Interface: I²C for control / configuration (internal registers)

• Operating voltage ranges:
    • DVDD / PVDD: 1.6 V to 3.6 V 
    • AVDD (analog supply): 1.7 V to 3.6 V

• Power consumption: Normal mode ~ 8 mA, power-down / standby mode ~ negligible current

• Internal filters: Digital interpolation / decimation filters with passband / stopband characteristics for single-speed and double-speed modes

• Gain error tolerances: ±5 % for both ADC and DAC

• Timing / serial port limits:
    • MCLK up to ~49.2 MHz 
    • SCLK up to ~26 MHz 
    • LRCK duty cycle, and SCLK / LRCK timing constraints for proper data alignment

• Package: QFN-20 / WQFN-20 layout, ~3×3 mm footprint, includes thermal pad for heat dissipation

• Operating temperature: –40 °C to +85 °C (typical for consumer-grade audio devices)

Applications

• Embedded audio output (e.g. voice, sound alerts)

• Voice / speech playback systems

• Portable / battery-powered audio devices

• Microcontroller-based audio systems (I²S output)

• Headphone or speaker drivers in small form factor gadgets

• Audio front-end for cameras, IoT modules, consumer electronics
