Resources for RAA2S4251
Description
The RAA2S4251B is a member of Renesas’ family of CMOS integrated circuits for highly accurate amplification and sensor-specific correction of differential bridge sensor signals. Featuring a maximum analog pre-amplification of 900 with analog sensor offset correction (XSOC), the RAA2S4251B is adjustable to nearly all resistive bridges.
Conditioning calculation is accomplished via a 16-bit RISC microcontroller. Calibration coefficients and configuration data are stored in the nonvolatile memory (NVM), which is reliable in automotive applications.
Measured values are provided via a ratio-metric analog output signal. End-of-line calibration is also supported through this output pin via a One-Wire Interface (OWI). Digital calibration helps keep assembly cost low as no trimming by external devices or lasers is needed. The RAA2S4251B is optimized for harsh automotive environments by over-voltage and reverse polarity protection circuitry, excellent electromagnetic compatibility, and multiple diagnostic features.
