General Description
The CS5530 is a highly integrated
ΔΣ Analog-to-Digital
Converter (ADC) which uses charge-balance techniques
to achieve 24-bit performance. The ADC is optimized for
measuring low-level unipolar or bipolar signals in weigh
scale,
process
control,
scientific,
and
medical
applications.
To accommodate these applications, the ADC includes
a very-low-noise, chopper-stabilized instrumentation
amplifier (12 nV/
√Hz @ 0.1 Hz) with a gain of 64X. This
device also includes a fourth-order
ΔΣ modulator fol-
lowed by a digital filter which provides twenty selectable
output word rates of 6.25, 7.5, 12.5, 15, 25, 30, 50, 60, 100,
120, 200, 240, 400, 480, 800, 960, 1600, 1920, 3200, and
3840 Sps (MCLK = 4.9152 MHz).
To ease communication between the ADC and a micro-
controller, the converter includes a simple three-wire se-
rial interface which is SPI and Microwire compatible with
a Schmitt-trigger input on the serial clock (SCLK).
High dynamic range, programmable output rates, and
flexible power supply options make this device an ideal
solution
for
weigh
scale
and
process
control
applications.
