Resolution is programmable from 5.5 mV/°C to 13.6 mV/°C, letting you trade noise immunity against temperature granularity: at the higher gain, a 1°C step produces 13.6 mV, easing the ADC's noise floor requirement. ## Supply flexibility and package fit Housed in a 5-lead SC-70 (SOT-353) package, the footprint is 2.0 mm × 2.1 mm — small enough to place close to the heat source on a dense PCB without routing a digital bus. ## Lifecycle and compliance reality Note the RoHS non-compliance: this part is not RoHS-compliant, which may restrict its use in EU or green-procurement BOMs unless an exemption applies.","metaTitle":"Texas Instruments LM94021BIMG Analog Temp Sensor, ±1.5°C","metaDescription":"Active TI LM94021BIMG analog local temp sensor, SC-70-5, ±1.5°C accuracy, 1.5-5.5V supply.
