6.5 A/D CONVERTER CHARACTERISTICS
(TA = -40 to +125°C unless otherwise specified)
Notes:
1.
Noise at VDD, VSS <10mV
2.
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)
