Product Summary
The ADUC824BSZ is a complete smart transducer front-end, integrating two high-resolution sigma delta ADCs, an 8-bit MCU, and program/data Flash/EE Memory on a single chip. This low power device accepts low-level signals directly from a transducer. The independent ADC(Primary and Auxiliary) ADUC824BSZ includes a temperature sensor and a PGA (allowing direct measurement of low-level signals). The ADC ADUC824BSZ with on-chip digital filtering is intended for the measurement of wide dynamic range, low-frequency signals, such as those in weigh scale, strain-gauge, pressure transducer, or temperature measurement applications.
