音频模/数转换器 IC 24-Bit Audio ADC
The PCM1850A/1851A is a highperformance, lowcost, singlechip stereo analogtodigital converter with a singleended analog front end that consists of a 6stereoinput multiplexer and widerange PGA. The PCM1850A/1851A includes a deltasigma modulator with 64times oversampling, a digital decimation filter and a lowcut filter that removes the dc component of the input signal. For various applications, the PCM1850A/1851A supports two modes master and slave and four data formats through a serial control interface, SPI for the PCM1850A and I2C for the PCM1851A. The PCM1850A/1851A is suitable for a wide variety of costsensitive DVD/CD/MD recorder and receiver applications where good performance and operation from a 5V analog supply and 3.3V digital supply is required. The PCM1850A/1851A is fabricated using a highly advanced CMOS process and is available in a small 32pin TQFP package.
