That ±2°C worst-case at the hot end is the number to stack into your error budget — the 25°C typical is tighter, but the system must hold at the thermal extremes. For a motor-winding or power-supply thermal trip, this accuracy class is adequate; for medical-grade thermometry, you would look at a higher-grade sensor. ## Package and mounting Housed in a 6-pin SOT-23 surface-mount package, the TMP122AIDBVR takes minimal board area. The SPI bus uses three signals (SCLK, SDI, SDO) plus the open-drain alert output (ALERT). Mounting is standard reflow; no special thermal pad is needed because the sensor measures its own die temperature through the package. ## Lifecycle and sourcing The TMP122AIDBVR is an Active, ROHS3-compliant part from Texas Instruments. No end-of-life notification is in effect.","metaTitle":"TMP122AIDBVR Digital Temperature Sensor, ±1.5°C Accuracy","metaDescription":"TMP122AIDBVR digital local temperature sensor from Texas Instruments. ±1.5°C accuracy, SPI output, -55°C to 150°C range.
