The ENS210 single-die sensor IC promises extremely accurate, pre-calibrated measurements of relative humidity and ambient temperature. Residing in a molded plastic surface-mount package measuring 2 mm x 2 mm x 0.75 mm, the sensor fits tight-quarter designs such as smart phones and wearable devices. It delivers a digital temperature output in Kelvin, accurate to a maximum ±0.2°C over the range 0°C to +70°C. Relative humidity measurements appear as a digital output accurate to a maximum ±3.5%. Shipped to customers as a calibrated unit, the sensor requires no trimming on the production line. It provides its digital outputs over an I2C interface, eliminating the need for signal processing by the host device’s applications processor or microcontroller. For power sensitive design, the ENS210 consumes 40 nA in stand-by mode and 7.1µA in active measurement mode (sampling at 1Hz). It operates from a wide input voltage range of 1.71V to 3.6V, which means that systems with a dual 1.8V/3.3V power supply need no additional level-shifting voltage regulator at the point of load. Pricing for the ENS210 is $1.90 each/100. For more information, go to
