Product Summary
The CS5503BP is a low-cost CMOS A/D converter ideal for measuring low-frequency signals representing physical, chemical, and biological processes. The CS5503BP utilizes charge-balance techniques to achieve and 20-bit performance with up to 4 kHz word rates at very low cost. The CS5503BP continuously sample at a rate set by the user in the form of either a CMOS clock or a crystal. On chip digital filtering processes the data and updates the output registers at up to a 4 kHz rate. The CS5503BP is designed to allow corner frequency settings from 0.5 Hz to 10 Hz in the CS5503. Thus, each converter rejects 50 Hz and 60 Hz line frequencies as well as any noise at spurious frequencies.
