TIMING CHARACTERISTICS (Figure 7)
(V
for MAX145, T
Note 1: Tested at V
Note 2: Relative accuracy is the deviation of the analog value at any code from its theoretical value after full-scale range has been
Note 3: Offset nulled.
Note 4: "On" channel is grounded; sine wave applied to "off" channel (MAX144 only).
Note 5: Conversion time is defined as the number of clock cycles times the clock period; clock has 50% duty cycle.
Note 6: The common-mode range for the analog inputs is from GND to V
Note 7: ADC performance is limited by the converter’s noise floor, typically 300µVp-p.
Note 8: Guaranteed by design. Not subject to production testing.
Note 9: Measured as V
