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 of damage.
For these operating currents, the following bit settings apply: SHUTDOWN<1:0> = 00, RESET<1:0> = 00,
VREFEXT = 0, CLKEXT = 0.
distortion or instability across this input range. Dynamic performance is specified at -0.5 dB below the maximum
signal range, V
See Appendix B.3 “Terminology and Formulas” for definitions.
Applies to all gains. Offset error is dependent on PGA gain setting.
This parameter is established by characterization and is not 100% tested.
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.
For these operating currents, the following Configuration bit settings apply: SHUTDOWN<1:0> = 11,
VREFEXT = 1, CLKEXT = 1.
This specification implies that the ADC output is valid over this entire differential range and that there is no
