TIMING CHARACTERISTICS (continued)
(VDD = +4.75V to +5.25V; unipolar/bipolar range; external reference mode, VREF = 4.096V; 4.7F at REF pin; TA = TMIN to TMAX;
unless otherwise noted. Typical values are at TA = +25°C.)
Note 1:
Accuracy specifications tested at VDD = 5.0V. Performance at power-supply tolerance limits is guaranteed by Power-
Supply Rejection test.
Note 2:
External reference: VREF = 4.096V, offset error nulled, ideal last-code transition = FS - 3/2LSB.
Note 3:
Ground “on” channel, sine wave applied to all “off” channels.
Note 4:
Guaranteed by design. Not tested.
Note 5:
Use static external load during conversion for specified accuracy.
Note 6:
Tested using internal reference.
Note 7:
PSRR measured at full scale. Tested for the ±10V (MAX127) and ±4.096V (MAX128) input ranges.
Note 8:
Not subject to production testing. Provided for design guidance only.
