TIMING CHARACTERISTICS—MAX1283
(Figures 1, 2, 5, 6; V
Note 1: Tested at V
Note 2: Relative accuracy is the deviation of the analog value at any code from its theoretical value after the full-scale range has
Note 3: Offset nulled.
Note 4: Ground the “on” channel; sine wave is applied to all “off” channels.
Note 5: Conversion time is defined as the number of clock cycles multiplied by the clock period; clock has 50% duty cycle.
Note 6: The common-mode range for the analog inputs (CH3–CH0 and COM) is from GND to V
Note 7: External load should not change during conversion for specified accuracy.
Note 8: ADC performance is limited by the converter’s noise floor, typically 300µVp-p. An external reference below 2.5V compro-
Note 9: Electrical characteristics are guaranteed from V
Note 10: AIN = midscale, unipolar mode. MAX1282 tested with 20pF on DOUT, 20pF on SSTRB, and f
Note 11: SCLK = DIN = GND, CS = V
