GENERAL DESCRIPTION
The EVAL-AD766XCB/AD767XCB is an evaluation board
for the AD766X/AD767X 16-bit A/D converter family. The
AD766X/AD767X family ( see ordering guide for product list )
is a high speed, successive approximation based architecture
with very high performance, low power family of 16-Bit ADCs
which operate from a single +5V supply with a 100kSPS to
1MSPS throughput rate range, and a flexible parallel or serial
interface. The AD766X/AD767X evaluation board is designed
to demonstrate the ADC's performance and to provide an easy
to understand interface for a variety of system applications. A
full description of the AD766X/AD767X is available in the
Analog Devices AD766X/AD767X data sheets and should be
consulted when utilizing this evaluation board.
The EVAL-AD766XCB/AD767XCB is ideal for use with
either the Analog Devices EVAL-CONTROL BOARD, or as a
stand-alone evaluation board. The design offers the flexibility
of applying external control signals and is capable of generating
16-bit conversion results on a parallel buffered outputs.
On-board components include an AD780, a +2.5V ultrahigh
precision bandgap reference, a signal conditioning circuit
with two op-amps and digital logic. The board interfaces with
a 96-way connector for the EVAL-CONTROL BOARD, a
20-pin IDC connector for serial output interface, and a 40-
pin IDC connector for parallel output data. SMB connectors
are provided for the low noise analog signal source, an exter-
nal master clock and an external start/convert input.
