General Description

The CS5532/34 are highly integrated

∆Σ Analog-to-Digi-

tal Converters (ADCs) which use charge-balance

techniques to achieve 24-bit 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 (CS5532) or four-channel (CS5534)

devices and include a very low-noise, chopper-stabilized

instrumentation amplifier (6 nV/

√Hz @ 0.1 Hz) with se-

lectable gains of 1×, 2×, 4×, 8×, 16×, 32×, and 64×.

These ADCs also include a fourth-order

∆Σ modulator

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.
