AUTOMOTIVE 8XC196KB

A to D CHARACTERISTICS

There are two modes of AD operation with and

without clock prescaler The modes are shown in the

table below In mode 2 with the clock prescaler dis-

abled the maximum XTAL1 frequency is 80 MHz

Accuracy will degrade at higher frequencies in this

mode The frequency divider option is provided to

obtain higher accuracy outside of the currently spec-

ified operating conditions

The converter is ratiometric so the absolute accura-

cy is directly dependent on the accuracy and stability

of VREF VREF must be close to VCC since it supplies

both the resister ladder and the digital section of the

converter

AD Converter Specifications

The specifications given below assume adherence

to the operating conditions section of this data

sheet Testing is performed in mode 2 with VREF e

512V and 8 MHz operating clock frequency
