MAX11206/MAX11207
It is not always necessary to transition to a high-imped-
ance state between channel selections, but depends on
the source analog signals as well as the control structure
of the multiplexed switches.
Digital Programmable Gain (MAX11206)
The MAX11206 offers programmable gain settings that
can be digitally set to 1, 2, 4, 8, 16, 32, 64, or 128. The
DGAIN_ bits in the CTRL3 register (see Table 14) config-
ure the digital gain setting and control the input referred
gain. The MAX11206’s input range is 0V to VREF/
gain (unipolar) or ±VREF/gain (bipolar). The MAX11206
always outputs 20 bits of data. But as this is a digital
programmable gain, the noise floor remains constant,
depending on the output rate setting. At an output rate of
10sps, as shown in Figure 4, the noise floor is such that
all gain settings from 1 to 64 provide 20 bits of noise-free
resolution. A gain setting of 128 at 10sps means the LSB
is below the noise floor. The MAX11206 digital gain is
beneficial for low-voltage applications that only require a
small portion of the 0V to VREF or ±VREF ranges.
