ADC Dual Delta-Sigma 48ksps 20-bit Serial 24-Pin SSOP T/R, PCM1800E/2K, Texas Instruments

The PCM1800 is a low-cost, single-chip stereoanalog-to-digital converter (ADC) with single-ended analog voltage inputs. The PCM1800 uses a delta-sigma modulator with 64 timesoversampling, 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.
