1μF at REFOUT; internal reference settling to 0.5LSB.
Relative accuracy is the analog value’s deviation (at any code) from its theoretical value after the full-scale range is calibrated.
V
REFIN
= 4.096V, offset nulled.
On-channel grounded; sine wave 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.
Guaranteed by design. Not subject to production testing.
Common-mode range for the analog inputs is from AGND to V
DD
.
External load should not change during the conversion for specified accuracy.
External reference at 4.096V, full-scale input, 500kHz external clock.
