The Silicon Labs SI7055-A20-IM is a digital temperature sensor designed for accurate temperature monitoring across a wide range. It features an industry-leading low power consumption and high accuracy of ±0.5°C across its entire operating voltage and temperature range.
This monolithic CMOS IC integrates a band-gap temperature sensor element, a 14-bit analog-to-digital converter, signal processing, and calibration data, all accessible via an I2C interface. The sensor operates within a wide voltage range of 1.9V to 3.6V and an extended temperature range of -40°C to +125°C, maintaining its accuracy throughout.
Factory-calibrated and stored in on-chip non-volatile memory, the Si7055-A20-IM ensures interchangeability without recalibration. It is available in a compact 3x3 mm DFN package, suitable for surface mounting. The low average current consumption makes it ideal for battery-powered applications.
Applications for this sensor include HVAC/R, thermostats, white goods, computer equipment, portable consumer devices, asset tracking, cold chain storage, battery protection, industrial controls, and medical equipment.
