2.1.3.2 Fixed Gain Single-Ended Output With Internal Reference (SE Int)

When R_S is populated REFIN is directly tied to GND and sets the offset for the output voltage with a fixed gain. The passive components of R9 and C11 are populated as a low-pass filter to attenuate high frequency noise components.

VDD and GND are accessible through the J2 terminal block. C7, C8 and C10 serve as decoupling capacitors for VDD and help keep the supply stable.

Using an oscilloscope, the user can observe the differential output signal on J3.3 (OUTP) with respect to J2.3 (GND).
