• Manufacturer Part Number: SAA-XC866-1FRA
• Description: 8-Bit Single-Chip Microcontroller
• Manufacturer: INFINEON [Infineon Technologies AG]

4.2.3
The values in the table below are given for an analog power supply between 4.5 V to
5.5 V. The ADC can be used with an analog power supply down to 3 V. But in this case,
the analog parameters may show a reduced performance. All ground pins (V
externally connected to one single star point in the system. The voltage difference
between the ground pins must not exceed 200mV.
