Note 1: ADC INL and DNL, offset, and gain are tested at DV
DD
= 1.8V, AV
DD
= 2.7V, f
SAMPLE
= 234ksps to guarantee performance
at f
SAMPLE
= 312ksps, DV
DD
≥ 2.7V and AV
DD
≥ 5.0V.
Note 2: Guaranteed by design. Not production tested.
Note 3: AV
DD
supply current contribution for this module.
Note 4: DNL and INL are measured between code 115 and 4095.
Note 5: Temperature sensor accuracy is tested using a 2.5084V reference applied to REFADJ.
Note 6: The maximum trip levels for the AV
DD
monitor are 5% below the typical charge-pump output value. The charge-pump output
voltage and the trip thresholds track to prevent tripping at -5% below the typical charge-pump output value.
Note 7: DV
DD
supply current contribution for this module.
Note 8: The normal operation and sleep mode supply currents are measured with no load on DOUT, SCLK idle, and all digital inputs
at DGND or DV
DD
. CLKIO runs in normal mode operation and idle in sleep mode.
