Supply rails and temperature — what they mean on site
This part needs two supply domains: an analog rail at 1.7 V to 1.9 V and a digital rail at 3 V to 3.6 V, with a separate 1.65 V to 1.95 V option on the digital side. That split is common for audio codecs that keep the analog front-end quiet while the digital core runs at a different level. No lab bench needed to verify the thermal margin; the range covers what a factory floor or an engine bay throws at it.
That makes it a safe pick for new designs and production BOMs — no last-time-buy scramble to plan for. If you are filling a BOM line or stocking a spare, this one is not going to disappear mid-cycle.
