Temperature Sensor Tackles Tough Error Budgets

The AS6200C digital temperature sensor provides a digital output and requires no user calibration or linearization and delivers highly accurate measurements in the temperature range -20°C to +10°C. The device promises to make it easier for designers of refrigerators and data loggers in cold-chain storage equipment to meet demanding targets for system-level accuracy. Measurements are accurate to ±0.2°C between -20°C and +10°C, the temperature range over which storage equipment for perishable goods operates. The sensor’s accuracy is guaranteed over the device’s supply voltage range of 1.8V to 3.6V.


The AS6200C integrates a sensor front end, 12-bit ADC and digital logic in a small WL-CSP. It provides a digital output over an I2C interface to any host microcontroller. The device performs on-board digital signal processing, which means that it needs no user calibration, and its linearized output requires no compensation by an external microcontroller. For technical information, an AS6200C datasheet is available upon request.
