Temperature Sensor Combines Accuracy, Ultra-Low Power Consumption, Ultra-Miniature Size

15 August 2016

Austrian company ams AG introduced an integrated digital temperature sensor offering a combination of low power consumption and high accuracy in a small physical package size. The 1.6mm x 1mm AS6200 typically draws 6 µA at a measurement rate of 4 samples per second. Its digital measurement outputs are accurate to ±0.4° C over the 0° C to 65° C temperature range.

Wearable devices and IoT sensor tags are examples of applications that could take advantage of the small size, low power consumption, and high accuracy of ams AG's AS6200 digital temperature sensor.

The factory-calibrated AS6200 integrates a complete temperature-sensing system in a single chip, making it easy for users to design the sensor into their space-constrained or battery-powered products. The device consists of a silicon band-gap 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 calibration, producing a 12-bit binary output offering 0.0625° C resolution.

The sensor's conversion rate can be set as low as once every four seconds to as high as eight samples per second. Operating from a supply range of 1.8 V to 3.6 V, the AS6200 draws just 1.5 µA at a measurement rate of 1 sample per second.

The chip’s I2C interface allows for two devices to be connected to one bus. The sensor also has a pin dedicated to an alert function, which triggers an interrupt at the host microcontroller when the measured temperature crosses a user-set high or low temperature threshold.

ams positions the tiny, ultra-low power AS6200 as creating new opportunities for manufacturers of battery-powered, mobile and wearable devices to implement digital temperature sensing into new designs without paying a power or space penalty. The space and power savings can benefit industrial process control solutions and Internet of Things applications such as cold-chain monitoring.

The AS6200 is available immediately in production volumes. Unit pricing is €0.49 in order quantities of 1,000.

An evaluation board is available online from the ams ICdirect online store. For more technical information, for sample requests, or to watch a video overview, go to the AS6200 product page at ams.com.
