Note 1:
For DC accuracy, the MAX1136/MAX1138 are tested at V
DD
= 5V and the MAX1137/MAX1139 are tested at V
DD
= 3V. All
devices are configured for unipolar, single-ended inputs.
Note 2:
Relative accuracy is the deviation of the analog value at any code from its theoretical value after the full-scale range and
offsets have been calibrated.
Note 3:
Offset nulled.
Note 4:
Conversion time is defined as the number of clock cycles needed for conversion multiplied by the clock period. Conversion
time does not include acquisition time. SCL is the conversion clock in the external clock mode.
Note 5:
A filter on the SDA and SCL inputs suppresses noise spikes and delays the sampling instant.
Note 6:
The absolute input-voltage range for the analog inputs (AIN0
–
AIN11) is from GND to V
DD
.
Note 7:
When the internal reference is configured to be available at AIN_/REF (SEL[2:1] = 11) decouple AIN_/REF to GND with a
0.01μF capacitor.
Note 8:
ADC performance is limited by the converter
’
s noise floor, typically 300μV
P-P
.
Note 9:
Measured as for the MAX1137/MAX1139
and for the MAX1136/MAX1138
Note 10:
A master device must provide a data hold time for SDA (referred to V
IL
of SCL) in order to bridge the undefined region of
SCL
’
s falling edge (see Figure 1).
Note 11:
C
B
= total capacitance of one bus line in pF.
Note 12:
f
SCL
must meet the minimum clock low time plus the rise/fall times.
