Vin Offset (VR1)
The volume to adjust the signal range (0V center assumed) with the A/D converter input range when a
waveform is input through AMP. IN.
A/D Full Scale (VR2)
The volume to adjust A/D converter VRB voltage.
Linearity (VR3)
The volume to adjust VRM (linearity) voltage. When DIR. IN input selected and it is supplied through the
capacitor, VR3 can be used to adjust the input offset voltage.
D/A Full Scale (VR4)
The volume to adjust D/A output full scale (–1V).
J1 (Input selection)
A: Shorts to adjust VRM voltage.
B: Shorts to supply DC voltage to Vin.
C: Shorts to select AMP.IN input.
D: Shorts to select DIR.IN input.
SW1
The switch for LINV High/Low.
SW2
The switch for MINV High/Low.
SW3 (Decimation)
The switch to select clock frequency decimation.
Switch position: decimation ratio
SW4 (D/A INV)
The switch for D/A converter output inversion.
