3. Key Product Features of the REF3040AIDBZR
The REF3040AIDBZR incorporates several outstanding characteristics that distinguish it among voltage reference chips.
High Accuracy and Stability: The REF3040AIDBZR boasts an initial accuracy of ±0.2% and a low temperature coefficient of 50ppm/°C. This ensures its output voltage remains highly stable even during temperature variations, providing a robust foundation for precision measurement and control.
Ultra-Low Power Consumption: With a maximum quiescent current (Iq) of just 50µA, the REF3040AIDBZR is exceptionally well-suited for portable and battery-powered devices. It effectively extends device runtime, making it an ideal choice for energy-efficient applications.
Low Dropout Operation: Requiring only 1mV dropout voltage, the REF3040AIDBZR maintains performance even when the supply voltage approaches the output voltage, further broadening its applicability in low-voltage systems.
Compact Packaging and High Integration: Housed in a small SOT-23-3 package, the REF3040AIDBZR occupies minimal board space. This makes it highly suitable for modern electronic designs with space constraints, contributing to product miniaturisation.
Stable Operation Without External Capacitors: Unlike some voltage reference chips requiring external load capacitors for stability, the REF3040AIDBZR is designed without any external capacitors. This simplifies circuit design, reduces costs, and makes it particularly suitable for intrinsically safe and explosion-proof applications.
Excellent load regulation and low noise: The REF3040AIDBZR delivers up to 25mA output current with low noise characteristics, ensuring output voltage purity—critical for high-precision analogue signal processing.
