, 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 full-scale range has
been calibrated.
Offset nulled.
Ground the “on” channel; sine wave is 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.
Note 6:
The common-mode range for the analog inputs (CH3–CH0 and COM) is from GND to V
DD1
.
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-
mises the performance of the ADC.
Note 9:
Electrical characteristics are guaranteed from V
DD1(MIN)
= V
DD2(MIN)
to V
DD1(MAX)
= V
DD2(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 f
SCLK
= 6.4MHz, 0 to 5V.
MAX1283 tested with same loads, f
SCLK
= 4.8MHz, 0 to 3V.
