The PCM3010 is a low-cost single-chip 24-, 16-bit stereo audio codec (ADC and DAC) with single-ended analog voltage input and output. Both the analog-to-digital converters (ADCs) and digital-toanalog converters (DACs) employ delta-sigma modulation with 64-times oversampling. The ADCs include a digital decimation filter with a high-pass filter, and the DACs include an 8-times-oversampling digital interpolation filter. The DACs also include a digital de-emphasis function. The PCM3010 accepts four different audio data formats for the ADC and DAC. The PCM3010 provides a power-down mode, which works on the ADC and DAC simultaneously. The PCM3010 is suitable for a wide variety of cost-sensitive consumer applications where good performance is required. The PCM3010 is fabricated using a highly advanced CMOS process and is available in a small 24-pin SSOP package.
