_______________________________________________________________________________________
Note 1:
Accuracy specifications tested at V
DD
= +5.0V. Performance at power-supply tolerance limit is guaranteed by power-supply
rejection test.
Note 2:
External reference: V
REF
= 4.096V, offset error nulled. Ideal last-code transition = FS - 3/2 LSB.
Note 3:
Ground “on” channel; sine wave applied to all “off” channels. V
IN
= ±5V (MAX1270), V
IN
= ±4V (MAX1271).
Note 4:
Guaranteed by design, not production tested.
Note 5:
Use static external loads during conversion for specified accuracy.
Note 6:
Tested using internal reference.
Note 7:
PSRR measured at full scale. Tested for the ±10V (MAX1270) and ±4.096V (MAX1271) input ranges.
Note 8:
Acquisition phase and conversion time are dependent on the clock period; clock has 50% duty cycle (Figure 6).
Note 9:
Not production tested. Provided for design guidance only.
