Electrical characteristics
7. For external triggers, a delay of 1/f

Equation 1: R
The formula above
allowed for an error below 1/4 of LSB. N = 12 (from 12-bit resolution) and k is the number of
sampling periods defined in the ADC_SMPR1 register.

1. Better performance could be achieved in restricted V
2. Based on characterization, not tested in production.
3. If an inverted reset signal is applied to PDR_ON, this value can be lowered to 1.7 V when the device
ADC accuracy vs. negative injection current: injecting a negative current on any analog input
pins should be avoided as this significantly reduces the accuracy of the conversion being
performed on another analog input. It is recommended to add a Schottky diode (pin to
ground) to analog pins which may potentially inject negative currents.
Any positive injection current within the limits specified for I
