Product details

Drift and noise across temperature

Low-frequency noise is specified at 27 µVp-p from 0.1 Hz to 10 Hz and 39 µVrms from 10 Hz to 10 kHz — these figures matter when the reference feeds a 16-bit or 18-bit ADC where the LSB noise budget is a few microvolts.

SOT-23-3 footprint and sourcing

Housed in a SOT-23-3 package (also known as TO-236-3 or SC-59), the REF3120AIDBZTG4 shares the same three-pin footprint as many other series references in this family, easing board layout for a second-source drop-in.

Frequently asked questions

What is the output voltage of REF3120AIDBZTG4?

Buyers need to confirm the reference voltage matches their design requirement before purchase.

Is REF3120AIDBZTG4 in stock at major distributors?

Sourcing buyers must know real-time availability to avoid production delays.

What is the price of REF3120AIDBZTG4 in 1000-piece quantities?

Transactional pricing determines BOM cost and influences distributor selection.

What is a direct replacement or equivalent for REF3120AIDBZTG4?

If the exact MPN is out of stock or obsolete, buyers need a drop-in alternative.

What is the pinout of REF3120AIDBZTG4?

Design engineers validate PCB footprint compatibility before ordering samples.

What is the lifecycle status of REF3120AIDBZTG4?

Brokers and buyers need to know if the part is active, NRND, or EOL to plan long-term supply.
