MAX11129–MAX11132
3Msps, Low-Power, Serial 12-/10-Bit,
8-/16-Channel ADCs
Averaging Mode
In averaging mode, the device performs the specified
number of conversions and returns the average for each
requested result in the FIFO. The averaging mode works
with internal clock only.
Scan Modes and Unipolar/Bipolar Setting
When the Unipolar or Bipolar registers are configured
as pseudo-differential or fully differential, the analog
input pairs are repeated in this automated mode. For
example, if N is set to 15 to scan all 16 channels and
all analog input pairs are configured for fully-differential
conversion, the ADC converts the channels twice. In this
case, the user may avoid dual conversions on input pairs
by implementing Manual mode or using Custom_Int or
Custom_Ext scan modes.
Register Descriptions
The MAX11129–MAX11132 communicate between the
internal registers and the external circuitry through the
SPI-/QSPI-compatible serial interface. Table 1 details the
register access and control. Table 2 through Table 14
detail the various functions and configurations.
For ADC mode control, set bit 15 of the register code
identification to zero. The ADC Mode Control register
determines when and under what scan condition the
ADC operates.
To set the ADC data configuration, set the bit 15 of the
register code identification to one.
