General Description
The 16-bit CS5529 is a low-power programmable

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.
(ADC)
which
includes
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 se-
lected 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, 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.
