NOTES:
4. Typical values are for AVCC = VCC = 2.7V to 5.0V, TA = +25°C.
5. TA = +25°C, AVCC = 5.0V; 2Hz to 20kHz Measurement Bandwidth, input signal 1VRMS, 1kHz Sine Wave.
6. When pin is open, voltage is pulled up through current source to VCC.
7. Limits should be considered typical and are not production tested.
8. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by characterization
and are not production tested.
