NCD2400M 1.6 General Conditions for Electrical Characteristics
Typical values are the result of engineering evaluations and are characteristic of the device at 25°C with VDD=3.3V and pins CP and CN biased to 1.65VDC. They are provided for informational purposes only and are not guaranteed by production testing. Unless otherwise specified, specifications cover the operating temperature range TA=-40ºC to +105ºC, and the supply voltage range VDD= 2.5V to 5.5V.
1.7 Capacitor Electrical Characteristics
Unless otherwise noted, characteristics are at the nominal operating temperature of 25 ±5°C with the CP and CN terminals biased at one-half of the supply voltage.
