CAPACITANCE 1
Note:
1. These parameters are not 100% tested, but are evaluated at initial characterization and at any time the design is modied where
capacitance may be affected.
Notes:
1. See “Switching Test Circuit” for test conditions.
2. These parameters are not 100% tested, but are evaluated at initial characterization and at any time the design is modied
where frequency may be affected.
3. tCF is a calculated value and is not guaranteed. tCF can be found using the following equation:
tCF = 1/fMAX (internal feedback) - tS.
