The ultimate combination of precision, ultra-low power consumption, and compact size.
Easy design support for IoT, mobile, and battery-powered applications

ams (SIX: AMS), a leading worldwide supplier of high performance sensors, today announced the launch of the AS6200, a highly integrated digital temperature sensor offering an industry-leading combination of low power consumption and high accuracy in a compact package. Measuring 1.6mm x 1mm, the AS6200's typical current consumption is 6µA at a measurement rate of 4 samples per second, and its digital measurement output is accurate to ±0.4°C.

The factory-calibrated AS6200 integrates all the functions required for a temperature sensing system into a single chip, enabling users to easily design the sensor into space-constrained or battery-powered applications.


The device consists of a silicon bandgap sensor, an analog-to-digital converter (ADC), a digital signal processor (DSP), and a serial I2C interface. The on-chip DSP handles all linearization and compensation functions and generates a 12-bit (0.0625°C resolution) binary output.

Despite its high integration, the AS6200 boasts extremely low current consumption. Operating over a 1.8-3.6V supply range, the AS6200 consumes only 1.5µA at a measurement rate of one sample. The conversion rate can be set from 0.25Hz to 8Hz. Lower conversion frequencies result in lower power consumption. In standby mode, where all functions of the chip are turned off except the serial interface, power consumption is only 0.1µA (typical).

The AS6200's compact size and ultra-low power performance create new opportunities for battery-powered mobile and wearable device manufacturers to implement digital temperature sensing in new designs without power or space constraints. Designs suitable for industrial and IoT applications, such as industrial process control and cold chain monitoring, can benefit from the space and power savings offered by the AS6200.

“Supported by ams’ proprietary low-power, high-sensitivity analog process, the AS6200, which is precisely calibrated before leaving the factory, offers the industry’s best combination of accuracy (maximum ±0.4°C over the range 0°C to 65°C), low power consumption and small size (1.6mm2),” said Christian Feierl, marketing manager at ams.

The sensor's I2C interface allows two devices to be connected to a single bus. The sensor features a dedicated pin for an Alert function, which triggers an interrupt on the host microcontroller when the measured temperature exceeds user-defined high/low temperature thresholds.

The AS6200 is available immediately in production quantities, priced at €0.49 per unit for orders of 1,000 units.
