Product details

2.5 V reference for precision analog rails

The REF03GSZ-REEL7: Output current capability is 10 mA, enough to bias multiple ADC reference inputs or a small sensor bridge without an external buffer.

Supply flexibility and quiescent budget

Input voltage range spans 4.5 V to 33 V, so the part runs from a regulated 5 V rail or directly off an unregulated 24 V industrial supply without a pre-regulator. Quiescent supply current is 1.4 mA — a consideration for loop-powered transmitters or battery-backed instrumentation where every milliamp matters.
