调研方向

阅读 AGENTS.md:356 中的接线表,并核实 sources/datasheet.txt 中引用的 TMP108 限值,尤其是第 6.1、6.3 和 9 节。更新该表,移除 5 V 选项,并注明文档规定的 1.4–3.6 V 范围;完成的标准是接线指南不再允许使用高于器件额定值的电源。

描述

audit:SBOS663A bug documentation impact:field-visible verdict:contradicts

AGENTS.md's hardware table tells contributors to wire the TMP108's V+
to either 3.3 V or 5 V:

| `V+`  | 3.3 V (or 5 V, datasheet range) | — |

AGENTS.md:356

5 V is not in the datasheet range. It exceeds both the recommended
operating maximum and the absolute maximum rating, and the parenthetical
attributes the permission to the datasheet.

Source

SBOS663A §6.3, Recommended Operating Conditions:

V+ Supply voltage 1.4 3.6 V

sources/datasheet.txt:191

SBOS663A §6.1, Absolute Maximum Ratings:

Supply voltage 4 V

sources/datasheet.txt:158

SBOS663A §6.1, footnote 1:

(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings

sources/datasheet.txt:167

SBOS663A §9:

The TMP108 operates on a power supply range from 1.4 V to 3.6 V. A power-supply bypass capacitor is

sources/datasheet.txt:1196

Why it matters

This is the wiring recipe a new contributor or agent follows before
running any of the five examples. 5 V is 1 V above the absolute maximum,
so following the instruction risks permanently damaging the part — and
unlike every other finding in this audit, no amount of driver-side
handling can recover from it.

The Pico de Gallo host adapter can source 5 V, so this is reachable, not
theoretical.

Suggested fix

Drop the 5 V option and state the documented range:

| `V+`  | 3.3 V (1.4–3.6 V per SBOS663A §6.3) | — |

Docs-only; no code, no semver impact.

Provenance

Raised by the datasheet compliance audit of PR #77 against the four
pinned sources. Found independently by two of the three audit agents.
Pre-existing on main; not introduced by #77.

Datasheet pinned at sha256:ec086250fc4331e7fc923be62173062bbf0fccedad6894c2741b73cd1c084556.
