SYMBOL
PARAMETER
Note 1: Tested at VDD1 = VDD2 = VDD(MIN), 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 the full-scale range has
been calibrated.
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 VDD1.
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 300Vp-p. An external reference below 2.5V compro-
mises the performance of the ADC.
Note 9: Electrical characteristics are guaranteed from VDD1(MIN) = VDD2(MIN) to VDD1(MAX) = VDD2(MIN). For operations beyond
this range, see Typical Operating Characteristics. For guaranteed specifications beyond the limits, contact the factory.
Note 10: AIN = midscale, unipolar mode. MAX1282 tested with 20pF on DOUT, 20pF on SSTRB, and fSCLK = 6.4MHz, 0 to 5V.
MAX1283 tested with same loads, fSCLK = 4.8MHz, 0 to 3V.
Note 11: SCLK = DIN = GND, CS = VDD1.
