Product details

2.5V reference rail — what the ±0.1% and 8 ppm/°C mean on your BOM

The REF5025AID is a 2.5V fixed-output series voltage reference from Texas Instruments' REF50xx family. Its ±0.1% initial tolerance is the spec that sets the ADC or DAC reference accuracy floor — if your 16-bit ADC needs a 2.5V reference to stay within 1 LSB at full scale, this part's 2.5 mV worst-case initial error is well inside the budget.

3 µVp-p noise — the spec that determines your ADC SNR ceiling

The part sinks 1.2 mA supply current and can source or sink up to 10 mA of output current.

Active production — no end-of-life clock ticking

That means Texas Instruments is still manufacturing it — no last-time-buy deadline, no scramble for a pin-compatible substitute. The base product number is REF5025, covering the whole family across different tolerance grades and packages.

It is surface-mount, supplied in Tube. The lead pitch is standard — no exotic footprint, no micro-BGA reflow profile.

Frequently asked questions

What is the output voltage and tolerance of REF5025AID?

Design engineers need to confirm it matches the required reference voltage and precision for their circuit.

Is REF5025AID obsolete or still in production?

Buyers and brokers need lifecycle status to avoid last-time buy or sourcing issues.

Where can I buy REF5025AID at the best price?

Sourcing buyers compare distributor pricing to minimize cost on BOM line items.

What is the exact package and pinout of REF5025AID?

Layout engineers need to verify footprint compatibility and pin assignments.

Does REF5025AID have a direct replacement from another manufacturer?

Maintenance techs or brokers need equivalents when primary part is unavailable or for second sourcing.

What is the typical noise level of REF5025AID?

High-precision applications require low noise; this spec drives part selection.
