The AS621x family of temperature sensors comes in three accuracy versions to give customers a wide choice to best match their requirements: ±0.2°C for the AS6212; ±0.4°C for the AS6214; and ±0.8°C for the AS6218. Not only has ams decreased the supply voltage range to a low level of 1.71 V, but by additionally increasing the number of I2C addresses to eight, customers now have the added flexibility to monitor up to 8 hot spots in their systems at minimum effort – especially during prototyping. As the AS621x is a complete digital temperature system, factory-calibrated to an accu-

racy up to +/-0.2°C, customers only need to solder the sensor solution onto their PCB to enjoy highest accuracy with no further calibration required. For greater sensitivity to temperature change, the resolution of the temperature value output has also increased to 16 bit. The devices draw 6µA typical at a measurement rate of four samples per second.
