The ±0.1% tolerance at 25 °C sets the accuracy floor; the 25 ppm/°C temperature coefficient dominates drift over the -40°C to 125°C range. Output current is rated at 10 mA, which is enough to bias a single ADC reference input or a handful of op-amp stages, but not enough to power a multi-channel simultaneous-sampling array without buffering. The 1 mA supply current is the quiescent draw from the input rail (12 V to 36 V) — plan for that in your power budget, especially in loop-powered or battery-backed designs.
Housed in a 5-lead SC-70-5 (SOT-353), this is a compact surface-mount package for dense PCB layouts. Verify your land pattern against the supplier device package drawing.
For dual-sourcing resilience, the ADR01BKSZ-REEL7 is a pin-compatible sibling with tighter ±0.05% tolerance and a lower 9 ppm/°C drift — worth qualifying if your BOM needs a precision upgrade path without a board spin.
