PCM1800数据手册集成电路（IC）的ADC/DAC-特殊用途规格书PDF

描述 Description

The PCM1800 is a low-cost, single-chip stereoanalog-to-digital converter (ADC) with single-ended analog voltage inputs. The PCM1800 uses a delta-sigma modulator with 64 times oversampling, including a digital decimation filter and a serial interface which supports both master and slave modes and four data formats. The PCM1800 is suitable for a wide variety of cost-sensitive consumer applications where good performance is required.

The PCM1800 is fabricated using a highly advanced CMOS process and is available in a small 24-pin SSOP package.
