PCM1802DB

Product Summary

The PCM1802DB is a high-performance, low-cost, single-chip stereo analog-to-digital converter with single-ended analog voltage input. The PCM1802DB uses a delta-sigma modulator with 64- or 128-times over-sampling, and includes a digital decimation filter and HPF (low cut filter) which removes the dc component of the input signal. For various applications, the PCM1802DB supports master and slave modes and four data formats in serial interface. The PCM1802DB is suitable for a wide variety of cost-sensitive consumer applications where good performance, 5-V analog supply, and 3.3-V digital supply operation is required. The PCM1802DB is fabricated using a highly advanced CMOS process and is available in the DB 20-pin SSOP package. The applications of the device are (1)AV Amp Receiver; (2)MD Player; (3)CD Recorder; (4)Multitrack Receiver; (5)Electric Musical Instrument.
