6.5 A/D CONVERTER CHARACTERISTICS

(TA = -40 to +125°C unless otherwise specified)

Notes:

Noise at VDD, VSS <10mV

With oscillator frequencies less than 1MHz, the A/D Converter accuracy is decreased.

6.6 TIMER CHARACTERISTICS

(TA = -40 to +125°C unless otherwise specified)

6.7 SPI CHARACTERISTICS

(TA = -40 to +125°C unless otherwise specified)

6.8 ARTIMER ELECTRICAL CHARACTERISTICS

(TA = -40 to +125°C unless otherwise specified)
