Note 1:
The MAX1036/MAX1038 are tested at V
DD
= 5V and the MAX1037/MAX1039 are tested at V
DD
= 3V. All devices are config-
ured 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:
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
include acquisition time. SCL is the conversion clock in the external clock mode.
Note 6:
The absolute voltage range for the analog inputs (AIN0
–
AIN11) is from GND to V
DD
.
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 675
.
Note 9:
ADC performance is limited by the converter
’
s noise floor, typically 1.4mV
P-P
.
Note 10:
Electrical characteristics are guaranteed from V
DD(min)
to V
DD(max)
. For operation beyond this range, see the
Typical
Operating Characteristics
.
Note 11:
Power-supply rejection ratio is measured as:
, for the MAX1037/MAX1039 where N is the number of bits (8) and V
REF
= 2.048V.
Power-supply rejection ratio is measured as:
, for the MAX1036/MAX1038 where N is the number of bits (8) and V
REF
= 2.048V.
Note 12:
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 (Figure 1).
