Maxim Integrated
24-Bit, Single-Channel, Ultra-Low-Power,
Delta-Sigma ADCs with GPIO
MAX11200/MAX11210
This selects all GPIO as outputs, as well as setting all
logic signals to 0 except the selected channel AIN1. To
select channel AIN3 next, it is best to set all switches to
a high-impedance state first (see Table 4b).
Then select channel AIN3 by driving IN3 high (see
Table 4c).
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 (MAX11210)
The MAX11210 offers programmable gain settings that
can be digitally set to 1, 2, 4, 8, or 16. The DGAIN_ bits in
the CTRL3 register (Table 14) configure the digital gain
setting and control the input referred gain. See Figure 4.
The MAX11210’s input range is 0V to VREF/gain (unipo-
lar) or ±VREF/gain (bipolar). The MAX11210 modulator
produces 32 bits of data, but only 24 bits of data are
used. For any given data rate, the noise floor remains
constant, independent of the digital gain setting. The
MAX11210 digital gain is beneficial for systems that can
afford averaging multiple readings for higher resolution.
