AMS launches an integrated digital temperature sensor which offers an industry-best combination of low power consumption and high accuracy in a small package.
The 1.6mm x 1mm AS6200’s typical current is 6µA at a measurement rate of 4 samples per second, and its digital measurement outputs are accurate to ±0.4°C.
The factory calibrated AS6200 integrates in a single chip the functions required in a temperature sensing system, making it easy for users to design the sensor into their space-constrained or
battery-powered products.
The device consists of a silicon bandgap sensor, an analog-to-digital converter, a digital signal processor and a serial I2C interface. The on-chip DSP handles all linearization and calibration, producing a 12-bit (0.0625°C resolution) binary output.
Despite its high level of integration, the AS6200 draws very little current. Operating from a supply range of 1.8V-3.6V, the AS6200 draws just 1.5µA at a measurement rate of 1 sample. The conversion rate can be set in a range from 0.25Hz to 8Hz. At lower conversion frequencies, power consumption is lower. In standby mode, in which all the chip’s functions are turned off except the serial interface, it draws just 0.1µA (typical).
Small and ultra low power, the AS6200 creates 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. Industrial process control solutions, and Internet of Things applications such as cold chain monitoring are significantly enhanced as space and power savings are realized when using the AS6200.
