DESCRIPTION

The PCM1800 is a low-cost, single-chip stereo analog-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.
