Multiplexed Analog Input and Output
The two differential analog inputs (INP and INM, or AUXP and AUXM) are multiplexed into the sigma-delta modulator.
The performance of the AUX channel is similar to the normal-input channel. The gain of the input amplifiers is set
through control register 4.
2.8.1
Multiplexed Analog Input
To produce excellent common-mode rejection of unwanted-signal performance, the analog signal is processed
differentially until it is converted to digital data. The signal applied to the INM and INP terminals should be differential
to preserve the device specifications. The signal source driving the analog inputs (INP and INM, or AUXP and AUXM)
should have a low source impedance to attain the lowest noise performance and accuracy. To obtain maximum
dynamic range, the signal should be ac-coupled to the input terminal. The analog input signal is self-biased to the
midsupply. Bit D4 of control register 1 selects these input sources. The default condition self-biases the input, since
the register default value selects INP and INM as the sources for the ADC.

Analog Output
OUTP and OUTM are differential outputs that can typically drive a 600-ohm load directly. Figure 2–18 shows the
circuit when the load is ground-referenced.
