Note 1: Tested at V
DD
= +5.0V (MAX1298) and V
DD
= +3.0V (MAX1299).
Note 2: Relative accuracy is the deviation of the analog value at any code from its theoretical value after the full-scale range has
been calibrated.
Note 3: Conversion time is defined as the number of clock cycles (64 for voltage measurements, 125 for temperature measure-
ments) multiplied by the internal clock period.
Note 4: Individual analog input voltages cannot extend beyond the power-supply rails.
Note 5: Input resistance is typically 250M&; 5?/SPAN>A limit reflects limitations in production testing.
Note 6: Specifications for full-on status assume continuous conversions. Power modes are software selected (Table 4).
Note 7: Measured at V
FS(+4.75V)
- V
FS(+5.25V)
for the MAX1298 and at V
FS(+2.7V)
- V
FS(+3.6V)
for the MAX1299.
Note 8: External load should not change during conversions for specified accuracy.
Note 9: Excludes noise and self-heating effects. Output error for MAX129_C guaranteed by design.
Note 10:External temperature sensing over -40?/SPAN>C to +85?/SPAN>C range, device at +25?/SPAN>C. Guaranteed by design.
