Low Pow er Stereo Audio CODEC With Headphone Amplifier Revision 2.0 December 2012 1 ES8388 GENERAL DESCRIPTION FEATURES ES8388 is a high performance, low power and low cost audio CODEC. It consists of 2-ch ADC, 2-ch DAC, microphone amplifier, headphone amplifier, digital sound effects, and analog mixing and gain functions. The device uses advanced multi-bit delta-sigma modulation technique to convert data between digital and analog. The multi-bit delta-sigma modulators make the device with low sensitivity to clock jitter and low out of band noise. ADC • 24-bit, 8 kHz to 96 kHz sampling frequency • 95 dB dynamic range, 95 dB signal to noise ratio, -85 dB THD+N • Stereo or mono microphone interface with microphone amplifier • Auto level control and noise gate • 2-to-1 analog input selection • Various analog input mixing and gains DAC • 24-bit, 8 kHz to 96 kHz sampling frequency • 96 dB dynamic range, 96 dB signal to noise ratio, -83 dB THD+N • 40 mW headphone amplifier, pop noise free • Headphone capless mode • Stereo enhancement • Bass and Treble • Various analog output mixing and gains Low Power • 1.8V to 3.3V operation • 7 mW playback; 16 mW playback and record System • I2C or SPI uC interface • 256Fs, 384Fs, USB 12 MHz or 24 MHz • Master or slave serial port • I2S, Left Justified, DSP/PCM Mode APPLICATIONS ORDERING INFORMATION • MID • MP3, MP4, PMP • Wireless audio • Digital camera, camcorder • GPS • Bluetooth • Portable audio devices ES8388 -40°C ~ +85°C QFN-28 Everest Semiconductor ES8388 Revision 2.0 December 2012 2 1 BLOCK DIAGRAM ..................................................................................... 4 2 28-PIN QFN AND PIN DESCRIPTIONS .........
