Product details

2.5V series reference — what the ratings mean for the BOM

Temperature drift is 20 ppm/°C over -40°C to +85°C. Input range is 4.5 V to 18 V; output current is 10 mA. Supply current is 600 µA typical, which keeps the self-heating low and makes this reference suitable for battery-powered instruments where every microamp matters.

Noise performance — why the 0.1 Hz to 10 Hz spec matters

Noise is 3.8 µVp-p over 0.1 Hz to 10 Hz and 6.8 µVrms over 10 Hz to 10 kHz.

Package and lifecycle

The device is housed in an 8-SOIC package (3.90 mm body width), surface-mount only. It is safe to qualify for new designs and volume production.

Frequently asked questions

Is MAX873BESA+T RoHS compliant?

Yes, it is ROHS3 compliant.

Can MAX873BESA+T be used as a replacement for MAX873BCSA?

The MAX873BCSA is the same die in an 8-SOIC package but in tube or bulk packaging rather than Tape & Reel. Electrically they are identical — the +T suffix only denotes the reeled shipping format. If your BOM calls for the tube variant, the +T version is a drop-in substitute as long as your assembly line accepts Tape & Reel.
