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.
