SYMBOL
PARAMETER
Note 1: MAX1280 tested at VDD1 = VDD2 = +5V, MAX1281 tested at VDD1 = VDD2 = +3V; 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 gain error and offset
error have been nulled.
Note 3: Offset nulled.
Note 4: Ground “on” channel; sine wave 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 absolute voltage range for the analog inputs (CH7–CH0, and COM) is from GND to VDD1.
Note 7: External load should not change during conversion for specified accuracy. Guaranteed specification of 2mV/mA is a result
of production test limitations.
Note 8: ADC performance is limited by the converter’s noise floor, typically 300Vp-p.
Note 9: Electrical characteristics are guaranteed from VDD1(MIN) = VDD2(MIN) to VDD1(MAX) = VDD2(MAX). For operations beyond
this range, see the Typical Operating Characteristics. For guaranteed specifications beyond the limits, contact the factory.
Note 10: AIN = midscale. Unipolar mode. MAX1280 tested with 20pF on DOUT, 20pF on SSTRB, and fSCLK = 6.4MHz, 0 to 5V.
MAX1281 tested with same loads, fSCLK = 4.8MHz, 0 to 3V. DOUT = FFF hex.
Note 11:
