Product Summary
The CS5532ASZ is highly integrated △Σ Analog-to-Digital Converter (ADC) which uses charge-balance techniques to achieve 24-bit performance. The CS5532ASZ is optimized for measuring low-level unipolar or bipolar signals in weigh scale, process control, scientific, and medical applications. To accommodate these applications, the CS5532ASZ comes as either two-channel devices and includes a very low noise chop-per-stabilized instrumentation amplifier (6 nV/√Hz @ 0.1Hz) with selectable gains of 1×, 2×, 4×, 8×, 16×, 32×, and64×.
