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.
