USING THE EVAL-ADATE304BBCZ

The EVAL-ADATE304BBCZ requires two voltage supplies (+21 V
and −10 V). The +21 V and −10 V supplies are enough to power
the entire board including the digital portion. The evaluation board
also has an SMA provision for both the inputs and outputs. The
EVAL-ADATE304BBCZ must be controlled through the USB and
can be used with the provided software for easy access to user
registers within the ADATE304. Designed to be interactive, the
EVAL-ADATE304BBCZ also features an LED array at the bottom
portion to notify the user that the correct data is being written to or
read from the device.

ADATE304 EVALUATION BOARD NOTES

When using the EVAL-ADATE304BBCZ, the following are some
important information to take note:
VREF_POT, the blue trimmer resistor located near the middle of
►
the EVAL-ADATE304BBCZ evaluation board, is used to adjust
the 5 V reference to the DUT.
The 5 V reference can be monitored on VREF_TP, which is
►
nearby, while adjusting VREF_POT. It has been set but can be
adjusted if desired.
Adjusting VPLUS, VDD, and VSS supplies between the two pow-
►
er supply ranges requires the use of VPLUS_POT, VDD_POT,
and VSS_POT. The values of power supply with respect to
the range used are listed in
inserted by default.

Place jumpers on VPLUS_JMPR, VCC_JMPR, VTT_JMPR,
►
VDD_JMPR, and VSS_JMPR during normal operation. These
terminals are also used to check the current flowing through the
supply.
Near GND_TP4 and the U3 IC are two LEDs. When activated,
►
SDI_SH LED indicates a serial data bus write to the ADATE304,
and the serial bus LED field reflects the data written out. Con-
versely, the SDO_SH LED, when activated, indicates a serial bus
read from the ADATE304 and that the EVAL-ADATE304BBCZ
serial bus LED bank is reading from the DUT.
The SDO_SH LED and serial bus LEDs do not reflect the whole
►
SPI read word, due to limits on the hardware circuitry or software
programming. Disregard LED CH1 to A0 when reading.
The device and FTDI microcontroller connection can be reset

manually by pressing DUTRST and USB_RS, respectively.
Handle with care and operate only if there are standoffs connect-
