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.
