General description
The MAX6607/MAX6608 precision, low-voltage, analog output temperature sensors are available in 5-pin SC70 and SOT23 packages. The devices have a +1.8V to +3.6V supply voltage range and 8µA supply current over the -20°C to +85°C temperature range. Accuracy is ±0.6°C (typ) from TA = +20°C to +50°C and is ±0.7°C (typ) from TA = 0°C to +70°C. The MAX6607/MAX6608 output voltage depends on its die temperature and has a slope of 10mV/°C and an offset of 500mV at 0°C.

CAUTION
The sample version of OSS-ECAL is not intended to be used with Threads (Tasks) or interrupts of different priority. Please do not use it as in the example below.
Example: If each sensor is assigned to the same ADC group and the OSS-ECAL API is executed in processes with different priorities, correct values may not be obtained.
ADC Gr0 Ch0 Temperature sensor AD22100A 100ms cycle Thread (low priority) to take in temperature
ADC Gr0 Ch1 Pressure sensor MPX5999D Event interrupts (high priority) to take pressure
