analog input mode (continued)
When pseudodifferential mode is selected, only two analog input channel pairs are available for the TLC3574
and TLC2574 and four channel pairs for the TLC3578 and TLC2578, because half the inputs are used as the
negative input.

reference voltage
The external reference is applied to the reference-input pins (REFP and REFM). REFM should connect to
analog ground. REFP is 4 V. Install decoupling capacitors (10
F in parallel with 0.1 F) between REFP and
REFM, and compensation capacitors (0.1
F) between COMP and AGND.
