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

AD7719 is applied to this socket.

Sub-Miniature BNC (SMB) Connector. The

analog input signal for the AIN2 input of the

AD7719 is applied to this socket.

Sub-Miniature BNC (SMB) Connector. The

analog input signal for the AIN3 input of the

AD7719 is applied to this socket.

Sub-Miniature BNC (SMB) Connector. The

analog input signal for the AIN4 input of the

AD7719 is applied to this socket.

Sub-Miniature BNC (SMB) Connector. The

analog input signal for the AIN5 input of the

AD7719 is applied to this socket.

Sub-Miniature BNC (SMB) Connector. The

analog input signal for the AIN6 input of the

AD7719 is applied to this socket.

Sub-Miniature BNC (SMB) Connector. The

master clock signal for the XTAL1 input of the

AD7719 is applied to this socket when the

board is configured for an externally applied

master clock.The AD7719 can be operated

with internal clock frequencies in the range

32.768 kHz +/-10%.

Sub-Miniature BNC (SMB) Connector. The

output value from AD7719 output pin P1/SW1

is available from this socket.

Sub-Miniature BNC (SMB) Connector. The

output value from AD7719 output pin P2/SW2

is available from this socket.

Sub-Miniature BNC (SMB) Connector. The

output value from the AD7719 I/O pin P3 is

available from this socket when P3 is

configured as an output. The input signal for

AD7719 I/O pin P3 is applied to this input

when P3 is configured as an input.

Sub-Miniature BNC (SMB) Connector. The

output value from the AD7719 I/O pin P4 is

available from this socket when P4 is

configured as an output. The input signal for

AD7719 I/O pin P4 is applied to this input

when P4 is configured as an input.

Sub-Miniature BNC (SMB) Connector. The

AD7719 current source pin IOUT1 is connected

to this socket.

Sub-Miniature BNC (SMB) Connector. The

AD7719 current source pin IOUT2 is connected

to this socket.

Sub-Miniature BNC (SMB) Connector. The

reference voltage for the REFIN1(-) input of

the AD7719 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 REFIN1(+) input of

the AD7719 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 REFIN2 input of the

AD7719 is applied to this socket when the

board is configured for an externally applied

reference voltage.

CONNECTORS

There are two connectors on the AD7719 evaluation

board as outlined in Table 5.

Table 5. Connector Functions

Connector

Functions

PCB Mounting Terminal Block. The

Digital Power Supply to the Evalua-

tion Board is provided via this Con-

nector if it is not being supplied via

SKT1 or SKT2.

PCB Mounting Terminal Block. The

Analog Power Supply to the Evalua-

tion Board must be provided via this

Connector.

SWITCHES

There is one switch on the AD7719 Evaluation board. SW1

is a push-button reset switch. Pushing this switch acti-

vates the active low RESET input on the AD7719 which

resets the control logic, interface logic, calibration coeffi-

cients, digital filter and analog modulator of the part to

power-on status.
