Budget REF3330 reference accuracy, supply headroom, load transients, output capacitance and settling before using nominal 3 V in conversion calculations.
Plan an OPA333 DC signal path with explicit feedback, bias return, output headroom, settling and ADC loading rather than assuming zero drift means zero error.
Configure TMP390 hot and cold thresholds with the correct resistor codes, hysteresis and output interpretation; distinguish trip testing from calibration.
Choose the correct TPS25947 eFuse variant, then check current-limit policy, inrush timing, reverse blocking and ready signals on a protected low-voltage setup.
Bring up a TLV320AIC3204 codec with deliberate supply sequencing, paged registers, audio clocks, routing and mute checks before judging recorded sound.
