_______________________________________________________________________________________
Note 1: Tested at VDD = +5V, unipolar input mode.
Note 2: Offset nulled.
Note 3: Time for reference to power up and settle to within 1 LSB.
Note 4: Conversion time is defined as the number of clock cycles multiplied by the clock period; clock has 50% duty cycle.
Note 5: The operational input voltage range for each individual input of a differentially configured pair is from GND to VDD. The
operational input voltage difference is from -VREF/2 to +VREF/2.
Note 6: See Figure 3 (Input Equivalent Circuit) and the
Sampling Error vs. Source Impedance curve in the Typical Operating
Characterisitcs section.
Note 7: Fast automated test, excludes self-heating effects.
Note 8: When CNVST is configured as a digital input, do not apply a voltage between VIL and VIH.
Note 9: Supply current is specified depending on whether an internal or external reference is used for voltage conversions.
Temperature measurements always use the internal reference.
ELECTRICAL CHARACTERISTICS (continued)
(VDD = +5V ±5%, fSAMPLE = 300kHz, fSCLK = 4.8MHz (50% duty cycle), VREF = 4.096V, TA = TMIN to TMAX, unless otherwise noted.
Typical values are at TA = +25°C.)
