Notes:
1. All minimum and maximum specifications are guaranteed and apply across the recommended operating conditions.
Typical values apply at nominal supply voltages and an operating temperature of 25 C unless otherwise stated.
2. Maximum power ramp-up time to reach V
DD
> 1.62 V should be less than 50 ms. Any ramp-up time slower than 50 ms
will require a software reset to ensure proper calibration of all internal circuits.
