S1-5 VIN-
Function: Connects -OUT of the single-ended to differential op-amp (AD8132) to ADC3. S1-5 and S1-
6 must be used together, when VIN- is in the ON position, VIN+ must also be in the ON
position to use the differential op-amp on channel ADC3 and ADC4.
Use:
Slide S1-5 to the ON Position to connect –OUT of the AD8132 to ADC3.
Slide S1-5 to the OFF Position to use ADC3 without the AD8132.
S1-6 VIN+
Function: Connects +OUT of the single-ended to differential op-amp (AD8132) to ADC4. When VIN+
is in the ON position, VIN- must also be in the ON position to use the differential op-amp on
channel ADC3 and ADC4.
Use:
Slide S1-6 to the ON Position to connect +OUT of AD8132 to ADC4.
Slide S1-6 to the OFF Position to use ADC4 without the AD8132.
S1-7 ADC4
Use:
Slide S1-6 to the ON Position to connect directly ADC4 of J3 header to ADC4 pin (pin #1) of
the ADuC7024.
Slide S1-6 to the OFF Position to disconnect ADC4 of J3 header from ADC4 pin (pin #1) of
the ADuC7024.
S1-8 LED
Function : Connects the DAC1 output to the green LED of the demo circuit, D1.
Use :
Slide S1-7 to the ON position to connect the DAC1 output to D1.
Slide s1-7 to the OFF position to use DAC1 output on J3 header.
