Parameters
(Note
This specification implies that the ADC output is valid over this entire differential range and that there is no
distortion or instability across this input range. Dynamic performance is 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, the CLKEXT bit should be equal to ‘0’.
