Ambient Operating Temperature
Storage Temperature
Note: 1. All voltages are with respect to ground.
Note: 2. AVSS, CVDSS1 and CVSS2 must be connected to the same analog ground plane.
Note: 3. The external p
ull-up resistors at the SDA and SCL pins should be connected to the maximum voltage or less.
Max is smaller value between AVDD+0.3V and 4.0V.
The voltage must not be applied to the CN1 and CN2 pins.
WARNING: Operation at or beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.
