ADC Transfer Functions
Figure 13 shows the unipolar transfer function for non-
temperature measurements, and Figure 14 shows the
bipolar transfer function used for temperature measure-
ments. Code transitions occur halfway between suc-
cessive-integer LSB values. Output coding is binary,
with 1 LSB = V REFADC /4096 for nontemperature mea-
surements, and 1 LSB = +0.125°C for temperature
measurements. All signed binary results use two’s com-
plement format.
V REFADC
ADC Conversion Scheduling
The MAX11008 ADC multiplexer scans and converts
the selected inputs in the order shown in Table 2 (see
the ADC Conversion Register (ADCCON) (Write Only)
section) when more than one channel is selected. The
results are stored in the FIFO when in ADC monitoring
mode. The BUSY signal is set at the start and reset at
the end of a scan except when the continuous convert
bit is set at which time BUSY does not then respond to
ADC conversions.
Writing a conversion command before a conversion is
complete cancels the pending conversion. Avoid
addressing the device using the serial interface while
the ADC is converting.

ADC Clock Modes

modes (known as clock modes) selectable through

internal reference selected) and the reference has not

been previously forced on (FBGON = 1), the device
inserts a typical delay of 72μs, for the reference to settle,
before commencing the ADC conversion. The reference
remains powered up while there are pending conver-
sions. If the reference is not forced on, it automatically
powers down at the end of a scan or when CONCONV in
the ADC Conversion register is set back to 0.
Internally Timed Acquisitions
and Conversions
Clock Mode 00
In clock mode 00, power-up, acquisition, conversion,
and power-down are all initiated by writing to the ADC
