Power supply ripple rejection measurement applies to a changing input voltage (V
IN
) waveform with a nominal 3.6 V baseline that drops to a 3 V value for 380 μs at a
4.6 ms repetition rate.

Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
