1.

Response time depends on system thermal mass (e.g. PCB dimensions and thickness) and airflow Refer to section 3.4 for

additional details.

2.

Initial value to 63% of total variation. Response time depends on system thermal mass and air flow.

3.

Temperature accuracy can be optimized for specified supply voltages upon request.
