noted. Typical values are at T
Note 1: The MAX1036/MAX1038 are 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 and
Note 3: Offset nulled.
Note 4: Ground ON channel; sine wave applied to all OFF channels.
Note 5: Conversion time is defined as the number of clock cycles (8) multiplied by the clock period. Conversion time does not
Note 6: The absolute voltage range for the analog inputs (AIN0–AIN11) is from GND to V
Note 7: When AIN_/REF is configured to be an internal reference (SEL[2:1] = 11), decouple AIN_/REF to GND with a 0.01µF capacitor.
Note 8: The switch connecting the reference buffer to AIN_/REF has a typical on-resistance of 675Ω.
Note 9: ADC performance is limited by the converter’s noise floor, typically 1.4mV
Note 10: Electrical characteristics are guaranteed from V
Note 11: Power-supply rejection ratio is measured as:
Note 12: A master device must provide a data hold time for SDA (referred to V
