Analog-To-Digital Converter
Electrical Characteristics
Table 9 shows the derated specifications for
extended temperature operation. See Figure 6 for the
ADC transfer characteristics.
NOTES:
1. The analog section of the ADC takes 16 × A2DCLK cycles per conversion,
plus 1 × A2DCLK cycles to be made available in the PCLK domain. An additional
3 × PCLK cycles are required before being available on the APB.
2. Data out = 0000000000 when the analog input equals the negative reference.
Data out = 1111111111 when the analog input equals the positive reference.
3. Guaranteed monotonic.
4. INL calculated as deviation from ‘best fit’ line after subtracting offset/gain errors over the center
90 % of full scale output range.
5. DC voltage error for the transition voltage from code 511 (0x1FF) to 512 (0x200)
6. The internal voltage reference is driven to nominal value VREF = 2.0 V. Using the Reference Multiplexer,
alternative low impedance (RS < 500) voltages can be selected as reference voltages.
The range of voltages allowed are specified above.
7. The analog input pins can be driven anywhere between the power supply rails.
If the voltage at the input to the ADC exceeds VREF+ or is below VREF-, the A/D result will saturate appropriately
at positive or negative full scale. Trying to pull the analog input pins above or below the power supply rails will
cause protection diodes to be forward-biased, resulting in large current source/sink and possible damage to the ADC.
8. Bandgap and other low-bandwidth circuitry operating. All other ADC blocks shut down.
