Renesas RAA2S425x

The RAA2S425x is Renesas’ CMOS family of signal conditioners for highly accurate amplification and sensor-specific correction of differential bridge sensor signals. Featuring extended analog sensor offset correction (XSOC), the RAA2S425x is adjustable to nearly all resistive bridges. The RAA2S425x ensures offset compensation, sensitivity, temperature drift, and nonlinearity. RAA2S425x delivers optimal solution for harsh automotive environment via overvoltage and reverse-polarity protection circuitry, excellent electromagnetic compatibility and ASIL-B compliance (offered by RAA2S4253B).

Key features

• High performance analog front end (AFE) for enhanced sensor signal conditioning
• Extended analog sensor offset correction (XSOC)
• Over-voltage and reverse polarity protection up to ±40V
• Compliance according to ISO26262 (offered by RAA2S4253B)

Additional features

• High performance analog front end (AFE) for enhanced sensor signal conditioning
• Extended analog sensor offset correction (XSOC)
• Digital compensation for offset, gain, and higher order nonlinearity as well as temperature coefficients of measured bridge sensor input signal
• Over-voltage and reverse polarity protection up to ±40V, robust EMC performance, and multiple diagnostic features
• High accuracy (0.35% – 1.0%) over a wide temperature range (-40°C to 150°C), offering effective ADC resolution of 13 to 18 bits
• Minimizing the need for external components besides reduced production costs by a single shot end-of-line (EOL) calibration procedure
• Compliance according to ISO26262 (offered by RAA2S4253B)

Applications

• Braking and transmission in xEV, PHEV, BEV and FCEV
• HVAC systems in xEV, PHEV, BEV and FCEV
