To capture Channel 1 waveform configure ADS1278EVM-CVAL PCB as follows and as shown in
.
•
Remove jumper
JP3
, Power down Buffer.
•
Set switches
S8
to right position to enable buffers in analog input signal paths.
•
Using jumper cable, ground the complementary analog input of Channel 1 by connecting test point
TP1, AGND,
to
J3.7, ANN1.
•
Set function generator to High Z mode, sine wave output, frequency = 500 Hz, Amplitude = 1 Vpp-diff,
DC offset = 500 mV, and enable the output.
•
Connect function generator negative output to
TP1, AGND,
and positive output to
