Test Conditions
Note 1:
This specification implies that the ADC output is valid over this entire differential range, i.e. there is no distortion or
instability across this input range. Dynamic Performance is specified at -0.5 dB below the maximum signal range,
VIN = -0.5 dBFS @ 50/60 Hz = 333 mVRMS, VREF = 2.4V.
2:
See terminology section for definition.
3:
This parameter is established by characterization and not 100% tested.
4:
For these operating currents, the following configuration bit settings apply: Config Register Settings:
SHUTDOWN<5:0> = 000000, RESET<5:0> = 000000; VREFEXT = 0, CLKEXT = 0.
5:
For these operating currents, the following configuration bit settings apply: Config Register Settings:
SHUTDOWN<5:0> = 111111, VREFEXT = 1, CLKEXT = 1.
6:
Applies to all gains. Offset error is dependant on PGA gain setting.
7:
Outside of this range, ADC accuracy is not specified. An extended input range of +/- 6V can be applied continuously to
the part with no risk for damage.
8:
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’.
