AS6223A-AWLT
Overview
The AS6223 is an ultra-low power, high-accuracy digital temperature sensor housed in a compact 4-pin WLCSP. Operating on a voltage range of 1.14V to 1.98V, it features an I2C interface and is specifically designed for space-constrained applications requiring minimal power consumption, such as mobile and wearable devices.
Why Choose This Part
The sensor offers an industry-leading balance of precision and power, consuming only 6uA at a 4Hz sample rate. Its tiny 0.82mm square footprint and extremely low supply voltage requirements make it compatible with the latest sub-1.8V low-power microprocessor rails.
Applications
Getting Started
Integration requires connecting the I2C SDA and SCL lines with appropriate pull-up resistors to the host MCU. For evaluation, use the AS6221/23 adapter boards or standard ams OSRAM development kits to verify accuracy across the -40C to +125C operating range. Developers should pay close attention to PCB thermal relief to ensure the sensor accurately measures the target environment rather than board heat.
