Parameters
(Note
This specification implies that the ADC output is valid over this entire differential range and that there is no dis-
tortion 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’.
