Sensirion has announced a new highly reliable digital temperature sensor series STS4xA that currently consists of two versions: STS41A-AD1B and STS41A-AW1B, with the latter offering optional wettable flank packaging to support automated optical inspection (AOI). This series is based on Sensirion’s CMOSens Technology and the integrated on-chip heater enables advanced on-board diagnosis (OBD), making it possible to perform a functionality and plausibility diagnosis instead of simple presence checks.
The cost-efficient STS4xA features an I²C interface and provides a wide supply voltage range. Thanks to its small size and four-pin dual-flat no-leads (DFN) package, the STS4xA can easily be integrated into a variety of automotive applications. Moreover, it meets relevant industry standards, such as 85 °C/85 % RH accelerated life tests.
