Note 1:
Tested at V
DD
= +5.0V (MAX1098) and V
DD
= +3.0V (MAX1099).
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 250MΩ; 5μA limit reflects limitations in production testing.
Note 6:
Specifications for full-on status assume continuous conversions. Power modes are software selected (Table 3).
Note 7:
Measured at V
FS(+4.75V)
- V
FS(+5.25V)
for the MAX1098 and at V
FS(+2.7V)
- V
FS(+3.6V)
for the MAX1099.
Note 8:
External load should not change during conversions for specified accuracy.
Note 9:
Excludes noise and self-heating effects. Output error for MAX109_C guaranteed by design.
Note 10:
External temperature sensing over -40°C to +85°C range, device at +25°C. Guaranteed by design.
