PCM3052A 具有微型放大器、偏置、MUX 和 PGA 的 24 位立体声音频编解码器
PCM3052A 描述
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.
