CN-0253
Setup
With the power output of the supply off, connect a +18 V power
supply to the J3-1 pin (VDD_EXT), a −18 V power supply to
the J3-3 pin (VSS_EXT), and the ground connection to the J3-2
pin (GND_EXT). Attach the test battery cells to the battery
connections. Ensure that the link headers are retained on the
battery connections that do not have batteries connected; that is, if
only using four batteries, the remaining four battery connections
should remain connected.
If computer control of the board is required, it is important to
remove the link headers: EN, A0, A1, and A2. If using the
EVAL-SDP-CS1Z, connect the EVAL-SDP-CS1Z to the EVAL-
CN0253-SDPZ using the 120-pin connector. Secure the connection
using the Nylon hardware.
Test
Apply power to the ±18 V supply. Use the EN link on the board
to enable the outputs from the ADG5408 multiplexers. Use the
A0, A1, and A2 links on the board to select the battery for testing.
The SMB connector, VOUT, can be used to connect to a separate
ADC evaluation board, such as the EVAL-AD7298SDZ or
manually tested using a digital voltmeter.
If computer control is required, connect the EVAL-SDP-CS1Z
to the PC using the USB cable. Launch the CN-0253 evaluation
software. The battery voltage can be tested as per the manual test.
An additional 5 V power supply pin is provided if using the
EVAL-SDP-CS1Z.
