ACHIEVING HIGH ACCURACY AND 13-BIT RESOLUTION WITH ST7LITE2 ADC

The state of control signals for this mode should be:

AMPSEL = 1

AMPCAL = 0

3) Amplifier output corresponds to 0V input (Offset Calibration)

To select this mode the state of the control signals for this mode should be:

AMPSEL= 1

AMPCAL = 1

tracted from each of the amplified-and-converted output digital codes. This offset can be

The above modes and the state of digital control signals required for each mode are shown in
