† Notice: Stresses above those listed under “Maximum

Ratings” may cause permanent damage to the device. This is

a stress rating only and functional operation of the device at

those or any other conditions above those indicated in the

operational listings of this specification is not implied.

Exposure to maximum rating conditions for extended periods

may affect device reliability.

Note 1: Capable of higher frequency operation depending on minimum and maximum duty cycles needed.

2: External oscillator input (OSC IN) rise and fall times between 10 ns and 10 µs used for characterization testing. Signal

levels between 0.8V and 2.0V with rise and fall times measured between 10% and 90% of maximum and minimum

values. Not production tested.

3: The reference input of the internal amplifier is capable of rail-to-rail operation.
