The LMP90080-Q1 is a high‑integration, multi‑channel 16‑bit sensor AFE with continuous background calibration and sensor diagnostics.
The LMP90080‑Q1 provides a 16‑bit Σ‑Δ ADC, programmable gain amplifiers, and a fully differential high‑impedance input multiplexer for up to four differential or seven single‑ended sensor channels. It features continuous background calibration and sensor diagnostics that operate without interrupting the signal path.
The device operates from a 4.75 V‑5.5 V analog supply, supports programmable gains from 1× to 128×, and includes two matched excitation current sources (100 µA‑1000 µA) for RTDs and thermocouples. It is offered in a 28‑pin HTSSOP package with a temperature range of –40 °C to +150 °C. This manual is written in Chinese.
