The CS5504 uses charge-balanced (delta-sigma) techniques to provide a low cost, high-resolution measurement at output word rates up to 200 samples per second. The on-chip digital filter offers superior line rejection at 50 Hz and 60 Hz when the device is operated from a 32.768 kHz clock (output word rate = 20 Sps). The CS5504 has on-chip self-calibration circuitry which can be initiated at any time or temperature to ensure minimum...
