TIMING CHARACTERISTICS
(V
(MAX1299), f
Note 1: Tested at V
Note 2: Relative accuracy is the deviation of the analog value at any code from its theoretical value after the full-scale range has
Note 3: Conversion time is defined as the number of clock cycles (64 for voltage measurements, 125 for temperature measure-
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 4).
Note 7: Measured at V
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°C to +85°C range, device at +25°C. Guaranteed by design.
