Function
9-way D-Type connector used to interface to other
systems.
36-way centronics connector used to interface to
PC via parallel printer port.
Sub-Miniature BNC (SMB) Connector. The
analog input signal for the AIN1 input of the
AD7707 is applied to this socket.
Sub-Miniature BNC (SMB) Connector. The
analog input signal for the AIN2 input of the
AD7707 is applied to this socket.
Sub-Miniature BNC (SMB) Connector. The
analog input signal for the AIN3 input of the
AD7707 is applied to this socket.
Sub-Miniature BNC (SMB) Connector. The
analog input signal for the LCOM input of the
AD7707 may be applied to this socket.
Sub-Miniature BNC (SMB) Connector. The
analog input signal for the HBIAS input of the
AD7707 may be applied to this socket.
Sub-Miniature BNC (SMB) Connector. The
analog input signal for the HCOM input of the
AD7707 may be applied to this socket.
Sub-Miniature BNC (SMB) Connector. The
reference voltage for the REFIN+ input of the
AD7707 is applied to this socket when the board
is configured for an externally applied reference
voltage.
Sub-Miniature BNC (SMB) Connector. The
reference voltage for the REFIN- input of the
AD7707 is applied to this socket when the board
is configured for an externally applied reference
voltage.
Sub-Miniature BNC (SMB) Connector. The
master clock signal for the MCLKIN input of the
AD7707 is applied to this socket when the board
is configured for an externally applied master
clock.The AD7707 can be operated with internal
clock frequencies in the range 500kHz to 5MHz.
CONNECTORS
There are two connectors on the AD7707 evaluation board as
outlined in Table 5.

Functions
PCB Mounting Terminal Block. The Digi-
tal Power Supply to the Evaluation Board
must be provided via this Connector if it is
not being supplied via SKT1 or SKT2.

log Power Supply to the Evaluation Board
must be provided via this Connector.
SWITCHES
There is one switch on the AD7707 Evaluation board. SW1
is a push-button reset switch. Pushing this switch activates the
active low RESET input on the AD7707 which resets the
control logic, interface logic, calibration coefficients, digital
filter and analog modulator of the part to power-on status.
