Tested at V
DD
= +2.7V.
Relative accuracy is the deviation of the analog value at any code from its theoretical value after full-scale range has been
calibrated.
Offset nulled.
“On” channel is grounded; sine wave applied to “off” channel (MAX144 only).
Conversion time is defined as the number of clock cycles times the clock period; clock has 50% duty cycle.
The common-mode range for the analog inputs is from GND to V
DD
(MAX145 only).
ADC performance is limited by the converter’s noise floor, typically 300μVp-p.
Guaranteed by design. Not subject to production testing.
Measured as V
FS(2.7V)
