“德州仪器 PCM1808PWR”详细介绍
描述
The PCM1808 is high-performance, low-cost, single-chip, stereo analog-to-digital converter with single-ended analog voltage input. The PCM1808 uses a delta-sigma modulator with 64-times oversampling and includes a digital decimation filter and high-pass filter that removes the dc component of the input signal. For various applications, the PCM1808 supports master and slave mode and two data formats in serial audio interface.
The PCM1808 supports the power-down and reset function by means of halting the system clock.
The PCM1808 is suitable for wide variety of cost-sensitive consumer applications where good performance and operation with a 5-V analog supply and 3.3-V digital supply is required. The PCM1808 is fabricated using a highly advanced CMOS process and is available in a small, 14-pin TSSOP package.
