General Description

The 16-bit CS5529 is a low-power, programmable

∆Σ

ADC

(Analog-to-Digital Converter), which includes

coarse/fine charge buffers, a fourth-order

∆Σ modulator,

a calibration microcontroller, a digital filter with program-

mable decimation rates, a 6-bit output latch, and a three-

wire serial interface. The ADC 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 Sps. 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 Sps or less, the filter

rejects both 50 Hz and 60 Hz simultaneously.

Low power, single conversion settling time, programma-

ble 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.
