LH79524/LH79525
Analog-To-Digital Converter
Electrical Characteristics
See Figure 10 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
2. The internal voltage reference is driven to nominal value VREF = 2.0 V. Using the Reference Multiplexer, alternative low impedance
3. The analog input pins can be driven anywhere between the power supply rails. If the voltage at the input to the ADC exceeds VREF+
4. Bandgap and other low-bandwidth circuitry operating. All other ADC blocks shut down.

domain. An additional 3 × PCLK cycles are required before being available on the APB.
(RS < 500) voltages can be selected as reference voltages. The range of voltages allowed are specified above. However, the on-chip
reference cannot drive the ADC unless the reference buffer is switched on.
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.
