Noise is specified at 25 µVp-p (0.1 Hz to 10 Hz) and 46 µVrms (10 Hz to 10 kHz), low enough for 12- to 14-bit conversion chains without an external filter. ## 8 ppm/°C tempco — why the W-grade matters for the BOM The ADR3533WARMZ-R7 carries an 8 ppm/°C temperature coefficient. The sibling ADR3533WBRMZ-R7 drops that to 5 ppm/°C while keeping the same ±0.1% tolerance, package, and pinout. For a design that needs tighter drift over temperature — say, a 16-bit ADC reference in an engine-control module — the B-grade is the parametric upgrade. For most 12-bit sensor interfaces and general-purpose rails, the W-grade's 8 ppm/°C is sufficient and avoids the premium. ROHS3 compliant. ## 8-MSOP footprint and automotive temperature range The 3.5 V minimum input allows operation from a 3.6 V nominal rail with headroom for dropout.","metaTitle":"ADR3533WARMZ-R7 Voltage Reference, 3.3V ±0.1%, 8-MSOP","metaDescription":"Analog Devices ADR3533WARMZ-R7 series voltage reference: 3.3V fixed output, ±0.1% tolerance, 8 ppm/°C drift, -40°C to 125°C.
