Description
96-way connector for I
External V
External +12 V, −12 V, and AGND power supply connector.
SMB socket for bipolar analog input signal. This is the input to the bias-up circuit.
SMB socket for output from bias-up circuit. The voltage at this socket is a unipolar signal.
Four SMB sockets for analog inputs V
SMB socket for the REF
SMB socket for an inverted SCL input signal. The signal applied to this socket is applied to the input of the 74HC05 inverter.
SMB socket for the SCL input signal to the SCL pin of the AD7993/AD7994.
SMB socket for an externally applied CONVST input signal.
SMB socket for external SDA input signal
SMB socket for SDA output signal from the SDA pin on the AD7993/AD7994. The data available at this socket is inverted
after being clocked out of the AD7993/AD7994.
SMB socket for SDA data to/from the AD7993/AD7994.
SMB socket for ALERT/BUSY output from the AD7993/AD7994.
