Note 1: Tested at VDD = +5V, COM = GND, unipolar single-ended input mode.
Note 2: Relative accuracy is the deviation of the analog value at any code from its theoretical value after offset and gain errors have
been removed.
Note 3: Offset nulled.
Note 4: On channel is grounded; sine wave applied to off channels.
Note 5: Conversion time is defined as the number of clock cycles times the clock period; clock has 50% duty cycle.
Note 6: Input voltage range referenced to negative input. The absolute range for the analog inputs is from GND to VDD.
Note 7: External load should not change during conversion for specified accuracy.
Note 8: When bit 5 is set low for internal acquisition, WR must not return low until after the first falling clock edge of the conversion.
TIMING CHARACTERISTICS (continued)
(VDD = VLOGIC = +5V ±10%, COM = GND, REFADJ = VDD, VREF = +2.5V, 4.7F capacitor at REF pin, fCLK = 7.6MHz (50% duty
cycle), TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.)
