Frequently Asked Questions
What is the output voltage accuracy of REF02?
The REF02AU provides 5.000V ±10mV (0.2%) initial accuracy at 25°C. When combined with the 8.5ppm/°C temperature coefficient, total error over the -40 to 85°C range is within ±0.12%, suitable for 10-12 bit system accuracy requirements.
What is the temperature output on REF02?
The REF02 includes a unique temperature-proportional voltage output (pin 3) that produces 2mV/°C. This can be used for system temperature monitoring or for software compensation of temperature-dependent errors without an additional sensor.
What input voltage does REF02 need?
REF02 requires minimum 7V input (2V dropout above 5V output) and supports up to 40V. This wide range allows direct operation from 12V or 24V supply rails. Quiescent current is approximately 1.2mA, resulting in low self-heating.
Can REF02 source and sink current?
Yes, REF02 is a series-type reference that can both source (up to 20mA) and sink current. This makes it suitable as both a positive and negative reference input for bipolar ADCs and DACs, unlike shunt references which can only sink current.
