Monolithic Sigma-Delta A/D Converters Offer 21-bit Resolution

Sensor-to-serial devices feature conditioning for strain-gages, thermocouples, RTDs, and low-level signals

The AD771X family of monolithic sensor-to-serial ICs uses oversampling (sigma-delta) a/d converter technology to provide conversions with better than 21-bit effective resolution and no missing codes discernible to 24 bits. They are designed to interface the output of sensors such as load cells, RTDs, thermocouples, as well as other low-level signals, to a digital system directly via a bidirectional serial port.
