Parameters
distortion or instability across this input range. Dynamic Performance specified at -0.5 dB below the
maximum signal range, V
See terminology section for definition.
This parameter is established by characterization and not 100% tested.
For these operating currents, the following bit settings apply: SHUTDOWN<1:0>=00, RESET<1:0>=00,
VREFEXT=0, CLKEXT=0.
For these operating currents, the following configuration bit settings apply: SHUTDOWN<1:0>=11,
VREFEXT=1, CLKEXT=1.
Applies to all gains. Offset error is dependant on PGA gain setting, see
Outside of this range, the ADC accuracy is not specified. An extended input range of ±6V can be applied
continuously to the part with no risk for damage.
For proper operation and to keep ADC accuracy, AMCLK should always be in the range of 1 to 5 MHz with
BOOST bits off. With BOOST bits on, AMCLK should be in the range of 1 to 8.192 MHz.
AMCLK = MCLK/PRESCALE. When using a crystal, CLKEXT bit should be equal to 0.
This parameter is periodically sampled and not 100% tested.
This specification implies that the ADC output is valid over this entire differential range and that there is no
