Analog-to-Digital Converter (ADC) Conversion Timing Specifications

Standard Operating Conditions (unless otherwise stated)
Param No. Sym. Characteristic Min. Typ. † Max. Units Conditions
AD20 TAD ADC Clock Period μs Using FOSC as the ADC clock source ADOCS = 0
μs Using ADCRC as the ADC clock source ADOCS = 1
AD21 TCNV Conversion Time Using FOSC as the ADC clock source ADOCS = 0
Using ADCRC as the ADC clock source ADOCS = 1
AD22 THCD Sample-and-Hold Capacitor Disconnect Time Using FOSC as the ADC clock source ADOCS = 0
Using ADCRC as the ADC clock source ADOCS = 1

* These parameters are characterized but not tested.

† Data in “Typ” column is at 3.0V, 25°C unless otherwise stated. These parameters are for design guidance only and are not tested.
