For a 16-bit ADC with a 2.5V reference, the noise contribution from the reference alone sits well below 1 LSB — the reference won't be the dominant noise source in the chain. Input voltage range spans 3.7V to 36V, so the reference can run from a 5V rail or a 24V industrial supply without a preregulator. Output current is rated 20mA, enough to bias multiple ADC inputs or a small sensor bridge. Supply current is 1.28mA typical — low enough that the reference's own draw doesn't dominate the power budget in a multi-rail system. ## Active production, ROHS3, standard SOIC footprint It is ROHS3 compliant, so it clears EU and global regulatory gates without an exemption. Packaged in an 8-SOIC (0.154\" width, 3.90mm body) — a standard surface-mount footprint that reflows on any lead-free profile.","metaTitle":"ISL21090BFB812Z-TK Renesas Voltage Reference, ±0.03%, 8-SOIC","metaDescription":"Renesas ISL21090BFB812Z-TK series voltage reference, ±0.03% tolerance, 7ppm/°C drift, 1µVp-p noise.
