Frequently Asked Questions
What output voltage accuracy does MAX6018AEUR16+ maintain across production for ADC reference designs?
MAX6018AEUR16+ specifies an output voltage range of 1.5968 V to 1.6032 V, which corresponds to an initial accuracy of ±0.2% around the 1.6 V nominal. This tight tolerance allows designers to use it as the ADC reference without trimming, reducing system calibration time on the production line.
Can MAX6018AEUR16+ operate when supplied directly from a 1.8 V LDO rail in a low-power design?
Yes. MAX6018AEUR16+ requires a minimum supply voltage of 1.8 V, and it will maintain its 1.6 V regulated output with the supply as low as 1.8 V. This 200 mV headroom is adequate for 1.8 V LDO-powered microcontroller systems, and the micropower quiescent current keeps the power budget impact negligible.
How does MAX6018AEUR16+ compare to a 1.25 V band-gap reference when used with a 12-bit ADC?
MAX6018AEUR16+ provides a 1.6 V reference, giving a full-scale ADC input range 28% larger than a 1.25 V reference for the same 12-bit resolution of 4096 counts. This wider span improves the effective voltage resolution per LSB, reducing the impact of ADC noise on measurement accuracy by approximately 0.4 µV/LSB compared to a 1.25 V reference.
What is the PCB footprint of the 3-pin SOT-23 package used for MAX6018AEUR16+?
The 3-pin SOT-23 package of MAX6018AEUR16+ measures 2.9 mm × 1.6 mm with a body height of approximately 1.1 mm and a 1.9 mm pin pitch. This is one of the smallest reference packages available, allowing placement directly adjacent to the VREF pin of a precision ADC or DAC without routing long traces.
For portable medical instruments requiring long battery life, how does MAX6018AEUR16+ minimize current draw?
MAX6018AEUR16+ is a micropower device with quiescent current typically below 100 µA, and the reference output draws current only when loaded. In duty-cycled sensor designs that sample at 1 Hz or less, the average power consumed by the voltage reference is well below 1 mW, extending battery life compared to standard 1 mA quiescent references.
