The CS5531/32/33/34 are highly integrated ΔΣ Analogto-
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 chopper-
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 ΔΣ 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 microcontroller,
the converters include a simple three-wire serial
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.
