The 16-bit CS5529 is a low-power programmable Delta-Sigma analog-to-digital (A/D) converter that includes coarse/fine charge buffers; a fourth-order Delta-Sigma modulator; a calibration microcontroller; a digital filter with programmable decimation rates; a 6-bit output latch; and a 3-wire serial interface. The A/D converter is designed to operate from single or dual analog supplies and a single digital supply. The digital filter is programmable with output update rates between 1.88 Hz to 101 Hz. These output rates are specified for XIN = 32.768 kHz. Output word rates can be increased by approximately 3x by using XIN = 100 kHz. The filter is designed to settle to full accuracy for the selected output word rate in one conversion. When operated at word rates of 15 Hz or less, the filter rejects both 50 Hz and 60 Hz simultaneously. Low power, single-conversion settling time, programmable output rates and the ability to handle negative input signals make this single- or dual-supply product an ideal solution for isolated and non-isolated applications. |
