Electrical Characteristics
All specifications apply in the circuit of Figure 4, with 4.0V ≤ V
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 2: All voltages are measured with respect to GND = 0V, unless otherwise noted.
Note 3: The absolute maximum junction temperature (T
junction-to-ambient thermal resistance (θ
maximum power dissipation will be reached only when the device is operated in a severe fault condition (e.g., when input or output pins are driven beyond the power
supply voltages, or the power supply polarity is reversed). Obviously, such conditions should always be avoided.
Note 4: Nonlinearity is defined as the deviation of f
the frequency range 1 Hz to 11 kHz. For the timing capacitor, C
Note 5: Human body model, 100 pF discharged through a 1.5 kΩ resistor.
