Frequently Asked Questions
What is the output voltage and accuracy of the REF3320AIDBZT?
The REF3320AIDBZT provides a precisely regulated 2.048 V output with an initial accuracy of 0.15%. This makes it well suited for use as a precision voltage reference in 12-bit and 16-bit ADC circuits where reference accuracy directly impacts conversion accuracy and system calibration requirements.
What is the minimum input voltage for the REF3320AIDBZT?
The device requires a minimum input voltage of 2.248 V, which is only 200 mV above the 2.048 V output. This low dropout characteristic makes it compatible with 3.3 V logic supply rails commonly found in microcontroller-based data acquisition and sensor interface designs.
How much output current can the REF3320AIDBZT source?
The REF3320AIDBZT can supply up to 5 mA of output current, sufficient to simultaneously drive the reference inputs of multiple ADC or DAC channels. This current capability also allows the reference output to be used directly as a small precision supply for sensor bridge circuits.
What package does the REF3320AIDBZT use, and is it RoHS compliant?
It comes in a 3-pin SOT-23 surface-mount package (JESD-30 code R-PDSO-G3), one of the smallest available for voltage references. The AIDBZT designation and e4 JESD-609 code confirm it is lead-free and RoHS compliant, suitable for all modern green-product electronics designs.
