Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifications do not apply when operating
the device beyond its specified operating conditions.

Note 3:
Nonlinearity is defined as the deviation of f
from V
IN
x (10 kHz/10 V
) when the circuit has been trimmed for zero error at 10 Hz and at 10 kHz, over
the frequency range 1 Hz to 11 kHz. For the timing capacitor, C
