CS5520-BS

Bridge Transducer A/D Converter 24Pin SOIC

Description

The CS5516 and CS5520 are 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 CS5516 or CS5520. The devices offer an on-chip software programmable instrumentation amplifier block, choice of DC or AC bridge excitation, and software selectable reference and signal demodulation.
