Si7021-A20-GM

Relative Humidity and Temperature Sensors

The Si7021-A20-GM digital relative humidity and temperature sensor integrates humidity and temperature sensor elements, an analog-to-digital converter, signal processing and an I2C interface in a single chip. The Si7021-A20-GM has a temperature accuracy of ±0.4 °C and a relative humidity accuracy of ±3%. The innovative CMOS design also offers the lowest power consumption in the industry for a relative humidity and temperature sensor. With full factory calibration, the Si7021-A20-GM requires no additional RH/temperature calibration during PCB assembly.

Quality Assurance, Environmental and Packaging Information

Silicon Labs targets a minimum of a 10-year lifecycle for all of its standard products and expects to produce the Si7021-A20-GM until at least June 2023.

The longevity date shown above is for the preferred revision of this part number, for a complete list of part number revisions, use the search button below.

As part of its ongoing commitment to supply continuity, Silicon Labs may provide pin-compatible and functionally equivalent replacement products if Silicon Labs determines, at its discretion, that supply chain adjustments, product improvements, market conditions, or similar business or technical issues make this necessary or advisable.

If for business, technical or other reasons beyond Silicon Labs’ reasonable control, Silicon Labs finds that it is necessary to discontinue a product, our policy is to issue an EOL notice that provides 6 months from notice to place final orders and 12 months from notice for final shipments. This policy complies with the JEDEC standard EIA/JESD48 that is commonly used in the semiconductor industry. We provide the required support for a product for its full life cycle.
