Signal ground is not connected to analog ground. Use this for differential input signal application.
W5
Signal ground is connected to analog ground. Use this for single-ended input signal application.
CS signal from J2-1 is routed through to control the SS function of the AMC7823. Normally used
for µ C operation.
W6
FSX signal from J2-7 is routed through to control the SS function of the AMC7823. Normally used
for DSP operation.
External reference input voltage via REF1 is routed to W1 pin 3.
W7
External reference input voltage via REF2 is routed to W1 pin 3.
TOUT signal is used to generate the external trigger for ADC conversion.
W8 Internal trigger for conversion is used.
BCLK or LRCLK signal, as selected by W9, is used to generate the external trigger for ADC
conversion.
BCLK signal from J4-3 is routed through to generate the external trigger for ADC conversion.
Normally used for µ C operation.
W9
LRCLK signal from J4-7 is routed through to generate the external trigger for ADC conversion.
Normally used for µ C operation.
