14-Bit ADC, 200ksps, +5V Single-Supply
with Reference
_______________________________________________________________________________________
5
Note 1: Tested at AVDD = DVDD = +5V, bipolar input mode.
Note 2: Relative accuracy is the deviation of the analog value at any code from its theoretical value after the gain error and offset
error have been nulled.
Note 3: Offset nulled.
Note 4: Conversion time is defined as the number of clock cycles multiplied by the clock period, clock has 50% duty cycle.
Includes the acquisition time.
Note 5: ADC performance is limited by the converter’s noise floor, typically 300Vp-p.
Note 6 When an external reference has a different voltage than the specified typical value, the full scale of the ADC will scale
proportionally.
Note 7: Electrical characteristics are guaranteed from AVDD(MIN) = DVDD(MIN) to AVDD(MAX) = DVDD(MAX). For operations beyond
this range, see the
Typical Operating Characteristics. For guaranteed specifications beyond the limits, contact
the factory.
Note 8: Defined as the change in positive full-scale caused by a ±5% variation in the nominal supply voltage.
