A/D converters

•

One A/D converter dedicated to power-supply voltage and die average temperature monitoring, providing a

10 bit conversion via Global SPI and with the capability to handle a queue of 4 conversion requests

•

One A/D converter dedicated to deployment circuitry voltage monitoring, providing a 10 bit conversion via

Global SPI and with the capability to handle one conversion request per time

•

One A/D converter dedicated to deployment leakage current diagnostic, providing a 10 bit conversion of

the measured leakage current via Global SPI; this current A/D converter is shared among all 8 deployment

channels

•

2 A/D converters dedicated to remote sensor interfaces, providing a 10 bit conversion of the sensor current

value and used for sensor communication decoding; each RSU channel have a dedicated current A/D

converter

•

2 A/D converters dedicated to DC sensor interfaces, one providing the voltage value (10 bit conversion) and

the other one providing the current value (10 bit conversion); the 2 A/D converters are shared among all 7

DC sensor channels. Conversions are provided via Global SPI, with the capability to handle a queue of 4

conversion requests
