GENERAL DESCRIPTION
This data sheet describes the setup and use of the AD7484
evaluation board. The AD7484 is a high speed, low power,
14-bit successive approximation ADC that operates from a
single +5 V supply and features throughput rates of up to
3 MSPS. Full details on the AD7484 are available in the AD7484
data sheet, which is available from Analog Devices, Inc., and
should be consulted in conjunction with this data sheet when
using the evaluation board.
On-board components include the following:
• AD780 pin programmable +2.5 V or +3 V ultra high
precision band gap reference
• AD829, AD8022, and AD711 op amps
• ADM809 reset generator
• Two 7S04 inverters
• 16-bit FCT245 type digital buffer.
Various link options are explained in detail in the Link Options
section.

Interfacing to this board is through a 96-way connector. This
96-way connector is compatible with the evaluation board
controller EVAL-CONTROL BRD2, which is also available
from Analog Devices. External sockets are provided for
CONVST, RD, WR, and CS signals, a bipolar analog input
signal, a biased up unipolar signal, optional external reference,
and offset voltages.
