It uses a CMOS bandgap architecture that achieves low quiescent current of 42uA (max) with no load, making it ideal for battery-powered applications. The 4.096V output voltage is specifically chosen for ADC\/DAC applications: at 4.096V full-scale, each LSB of a 12-bit ADC represents exactly 1mV (4096mV\/4096 steps = 1mV\/step), simplifying digital-to-voltage conversion. The device can sink and source up to 10mA of output current. The output noise is 18uVpp (0.1-10Hz), low enough for 12-bit ADC systems. The line regulation is 40ppm\/V and load regulation is 20ppm\/mA. Unlike shunt references (like LM4040), the REF3040 is a series reference that draws only quiescent current from the input supply, not the full load current. This results in significant power savings when the load is light. The device requires no external capacitor for stability but a 0.1uF output capacitor improves transient response and noise. The input voltage must be at least 200mV above the output (VOUT + 0.2V minimum). The 4.096V output from a 5V supply leaves 0.904V headroom, which is comfortable. The -AIDBZR suffix specifies SOT-23-3, automotive grade, tape-and-reel.","pin_description":"
