Bandgap Voltage Reference Mode Selection.

Bandgap Voltage Reference Mode SelectionSpecifies the operating mode for the bandgap voltage reference circuit during low power modes. The bandgap reference provides a stable, temperature-compensated voltage reference that is fundamental to many analog and digital circuits. Different modes offer varying levels of accuracy, power consumption, and temperature stability to optimize system performance for specific applications.

Bandgap Reference Functions:

• Provides temperature-compensated voltage reference (~1.2V typical)
• Foundation for LDO regulation and analog circuit biasing
• Critical for ADC reference voltage stability
• Affects overall system voltage regulation accuracy

Mode Characteristics: Different bandgap modes typically offer:

• High Performance: Best accuracy and temperature stability, higher power
• Standard: Balanced accuracy and power consumption
• Low Power: Reduced power consumption with acceptable accuracy
• Ultra Low Power: Minimal power but reduced accuracy and stability

註

Mode Selection Criteria:

• Choose based on required voltage regulation accuracy
• Consider temperature range and stability requirements
• Evaluate power consumption constraints

• Account for wake-up time and settling requirements

  Precision Applications:

  // Use high-performance bandgap for precision applications
  config.bandgapMode = BandgapMode::HIGH_PERFORMANCE;
  // Best accuracy for precision ADC and analog circuits
