An internal test DAC (TDAC) provides a known voltage to the ADC to diagnose the operation of the signal chain. The positive and negative TDAC voltages are output on AIN6 (J3:7) and AIN7 (J3:8), respectively. Do not load AIN6 and AIN7 when the test signals are enabled because the TDAC outputs are unbuffered.
