Product Summary

The CS5520-BP is a 16bit/20-bit bridge transducer a/d converter. The CS5520-BP is complete solutions for digitizing low level signals from strain gauges, load cells, and pressure transducers. Any family of mV output transducers, including those requiring bridge excitation, can be interfaced directly to the CS5520-BP. The CS5520-BP offer an on-chip software programmable instrumentation amplifier block, choice of DC or AC bridge excitation, and software selectable reference and signal demodulation. The CS5520-BP uses delta-sigma modulation to achieve 16-bit resolution at output word rates up to 60 Sps. The CS5520-BP achieves 20-bit resolution at output word rates up to 60 Sps. The CS5516 and CS5520-BP sample at a rate set by the user in the form of either an external CMOS clock or a crystal. On-chip digital filtering provides rejection of all frequencies above 12 Hz for a 4.096 MHz clock.
