What is PREF4132B40DBVRQ1 used for?
PREF4132B40DBVRQ1 is designed for automotive electronic control units (ECUs) requiring a stable, low-noise 4.096 V reference for high-resolution ADC and DAC converters in engine management, battery management systems, and ADAS sensor modules. The 12 ppm/°C temperature coefficient ensures reference voltage drift remains below 0.5 mV over the -40°C to +125°C automotive temperature range, maintaining ADC accuracy across all operating conditions. It is also suited for industrial precision measurement instruments where a 4.096 V reference simplifies per-bit scaling in 12-bit and 16-bit converter designs.

Frequently Asked Questions
What is the output voltage accuracy and temperature coefficient of PREF4132B40DBVRQ1?
PREF4132B40DBVRQ1 provides a nominal 4.096 V output with accuracy within ±2 mV, corresponding to output limits of 4.093952 V to 4.098048 V. Its 12 ppm/°C temperature coefficient limits output drift to approximately 1.5 mV over the full -40°C to +125°C automotive temperature range.
For which automotive applications is PREF4132B40DBVRQ1 most appropriate given its qualification level?
PREF4132B40DBVRQ1 is designed for automotive ECU applications requiring AEC-Q100 qualification, including engine control units, battery management systems for hybrid and electric vehicles, and ADAS perception modules. The 4.096 V reference conveniently maps to 1 mV per LSB in a 12-bit ADC operating at full-scale 4.096 V, simplifying software calibration in safety-critical automotive sensing.
How does a 12 ppm/°C temperature coefficient benefit a 16-bit ADC reference design compared to a 50 ppm/°C alternative?
A 50 ppm/°C reference on a 4.096 V output drifts approximately 20 mV over 100°C, introducing up to 320 LSB error in a 16-bit ADC. PREF4132B40DBVRQ1 at 12 ppm/°C limits the same drift to under 5 mV, reducing temperature-induced error to less than 80 LSBs and allowing the converter to maintain 13-bit effective accuracy over the full automotive temperature range.
Can PREF4132B40DBVRQ1 drive multiple ADC reference inputs simultaneously, and what is its output current limit?
PREF4132B40DBVRQ1 supports a maximum output current of 10 mA, which is sufficient to drive the reference input of multiple low-power 12-bit or 16-bit SAR ADCs in parallel. Each ADC reference input typically draws between 0.1 mA and 1 mA, so a single PREF4132B40DBVRQ1 can supply 5 to 10 ADC references without significant voltage drop or accuracy degradation.
