General Description
The CS5531/32/33/34 are highly integrated
Σ Analog-
to-Digital Converters (ADCs) which use charge-balance
techniques to achieve 16-bit (CS5531/33) and 24-bit
(CS5532/34) performance. The ADCs are optimized for
measuring low-level unipolar or bipolar signals in weigh
scale,
process
control,
scientific,
and
medical
applications.
To accommodate these applications, the ADCs come as
either
two-channel
(CS5531/32)
or
four-channel
(CS5533/34) devices and include a very low noise chop-
per-stabilized instrumentation amplifier (6 nV/
√Hz @ 0.1
Hz) with selectable gains of 1×, 2×, 4×, 8×, 16×, 32×, and
64×. These ADCs also include a fourth order
Σ modu-
lator followed 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 ADCs and a micro-
controller, the converters include 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 makes these ADCs ideal
solutions
for
weigh
scale
and
process
control
applications.
