ES8328

ES8328 Low Power Stereo Audio CODEC With Headphone Amplifier GENERAL DESCRIPTION ES8328 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. APPLICATIONS GPS Bluetooth MP3, MP4, PMP Cell phone Digital camera, camcorder Portable audio devices FEATURES 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 3-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, capless option 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 ORDERING INFORMATION ES8328 -40°C ~ +85°C QFN-28 Revision 1.0 1 8/15/2009 Everest Semiconductor ES832...
