产品概述
The PCM3052A is a low-cost, single-chip, 24-bit stereo audio codec (ADC and DAC) with single-ended analog voltage input and output. It also has an analog front end consisting of a 34-dB microphone amplifier, microphone bias generator, 2 stereo multiplexers, and a wide-range PGA. Analog- to-digital converters (ADCs) employ delta-sigma modulation with 64-times oversampling. On the other hand, digital-to-analog converters (DACs) employ modulation with 64- and 128-times oversampling. ADCs include a digital decimation filter with a high-pass filter, and DACs include an 8-times oversampling digital interpolation filter. The PCM3052A has many functions which are controlled using the I2C interface: DAC digital de-emphasis, digital attenuation, soft mute etc. The PCM3052A also has an S/PDIF output pin for the DAC digital input. The power-down mode, which works on ADCs and DACs simultaneously, is provided by an external pin. The PCM3052A is suitable for a wide variety of cost-sensitive PC audio (recorder and player) applications where good performance is required. The PCM3052A is fabricated using a highly advanced CMOS process and is available in a small 32-pin VQFN package.
