I
Connect capacitor to ground to set oscillation frequency (220 pF for 500 kHz, 1 nF for 100 kHz) when
the internal oscillator is selected; connect clock signal when an external oscillator is used
FAULT0

I
Connect 120 k
resistor to AGND to set oscillation frequency (either 500 kHz or 100 kHz). Not need-
ed if an external clock is used.
SHUTDOWN

stg
Stresses beyond those listed under
“
absolute maximum ratings
”
may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under
“
recommended operating conditions
”
is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
