TIMING CHARACTERISTICS
(V
2MHz; T
Note 1: Accuracy specifications tested at V
Note 2: External reference: V
Note 3: Ground “on” channel; sine wave applied to all “off” channels. V
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.
