2. Make sure which IC is soldered on the Demoboard.
3. Set Jumper as described above.
− Choose an output impedance.
− Choose the gain.
4. Connect a 2.7 to 5.5V power supply (VDD and GND).
5. Connect a differential signal source. For example differential sinus signal.
6. Measure on the measuring points J6(OUT+) and J5(OUT-) and J15(BIAS-GND).
Note: It’s possible to connect headphones or speakers (4Ohm or 8Ohm Impedance) to the outputs. Make sure the onboard Output
Impedance is set to 0Ohm with removing Jumper J7 (F).
