Note 1:
MAX1280 tested at V
DD1

DD2
= +5V, MAX1281 tested at V
DD1
= V
DD2
= +3V; COM = GND; unipolar single-ended
input mode.
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.
Offset nulled.
Ground “on” channel; sine wave applied to all “off” channels.
Conversion time is defined as the number of clock cycles multiplied by the clock period; clock has 50% duty cycle.
The absolute voltage range for the analog inputs (CH7–CH0, and COM) is from GND to V
DD1
.
External load should not change during conversion for specified accuracy. Guaranteed specification of 2mV/mA is a result
of production test limitations.
ADC performance is limited by the converter’s noise floor, typically 300μVp-p.
Electrical characteristics are guaranteed from V

= V
DD2(MIN)
to V
DD1(MAX)
= V

. For operations beyond
this range, see the
Typical Operating Characteristics
. For guaranteed specifications beyond the limits, contact the factory.
