The device integrates support one fully-differential analog microphone input and mono line output driver. The mono 24-bit multi-bit sigma delta ADC with digital decimation filters has programmable gain with automatic gain control (AGC). Digital audio output word length from 8-24 bits and sampling rates from 8kHz to 48kHz are supported. A multi-bit sigma delta DAC is used with digital audio input word length from 8-24 bits and sampling rates from 8 to 48kHz. The parametric Equalizer consists of 3-band EQ for playback path. Gain, center frequency, and bandwidth of each band EQ can be programmed independently to compensate frequency response of speakers, and to meet various user preferences. The AC102 provides many formats of serial audio data interface to the input of the DAC or output from the ADC through LRCK, BCLK and SDIN/SDOUT pins. These formats are I2S, left justified, right justified, PCM mode. The AC102 is controlled through TWI (2-wire serial interface). The clock supports up to 400 KHz rate. It works only in the slave mode. Applications • Portable audio applications • Digital Cameras and video cameras • Wireless headset • Tablets and e-Books |
