Supply current, input bias, and offset — the signal-chain budget
The MAX4163EBL+T: Each channel draws 25 µA supply current, so the dual amplifier consumes 50 µA total quiescent — negligible in a 24/7 sensor node but worth tracking against the system power budget.
Temperature grade and supply range
Supply span runs from 2.5 V minimum to 10 V maximum, so it works on a single Li-ion cell (3.0-4.2 V), a 3.3 V rail, or a 5 V regulated bus without needing a separate supply.
RoHS3 compliant — no exemption-based restrictions on the six restricted substances plus the four phthalates.
