TMP112-Q1

I²C digital temperature sensor (range-qualified accuracy)

A local digital temperature sensor. TMP112-Q1 specifies ±0.5°C maximum error over 0–65°C and ±1°C over −40–125°C; do not inherit TMP112D-Q1 accuracy or supply limits from the shared page.

In one sentence: The reviewed source states AEC-Q100 and a −40°C to +125°C range, but no numeric Grade. Do not derive the grade from temperature. TI lists Functional Safety-Capable with functional-safety documentation. The system ASIL claim still requires ECU-level verification.

Orderable variants (OPNs)

The GPN is for selection; the full OPN is for ordering. These examples were observed on the verification date, not live stock. Variants may differ in package, temperature, gain/threshold and, for PMICs, NVM/sequencing. Distinguish TA from TJ in the exact datasheet.

FAQ

Is TMP112-Q1 automotive qualified?

The reviewed source states AEC-Q100 and a −40°C to +125°C range, but no numeric Grade. Do not derive the grade from temperature.

Which OPNs are available for TMP112-Q1?

TI's product page currently lists 1 OPN; this page shows the first 1 OPN, including TMP112AQDRLRQ1. Use the full OPN for ordering, not the GPN.

Where can I check price, stock and lead time for TMP112-Q1?

NuAxi does not invent stock or pricing on this page. Use TI's ordering page and authorized distributors for live stock, lead time and quotations; verify package, temperature, pinout and software before substitution.
