Description
Flag Output. This pin is used to transmit data from the
processor to the SDA pin of the AD7993/AD7994.
Flag Output 1. This pin is used to generate the CONVST
pulse to initiate a conversion.
Flag Input. This pin is used to transmit data into the
processor from the SDA pin on the AD7993/AD7994.
Flag Output 0. This pin is used to provide the SCL signal
to the AD7993/AD7994 from the processor.
Interrupt Receive. This pin is used to provide an
ALERT/BUSY signal from the AD7993/AD7994 to the
processor.
Analog Ground. This pin is connected to the analog
ground plane of the EVAL-AD7993CB/AD7994CB.
Analog 3 V/5 V Supply. This pin is used to supply the 3 V/5 V
supply to the AD7993/AD7994 via LK9.
−12 V Supply. This pin is used to supply the −12 V power
supply voltage to the EVAL-AD7993CB/AD7994CB.
+12 V Supply. This pin is used to supply the +12 V power
supply voltage to the EVAL-AD7993CB/AD7994CB.
