INTRODUCTION
This data sheet describes the evaluation board for the AD7482,
which is a high speed, low power, 12-bit successive approxima-
tion ADC. This part operates from a single 5 V supply and
features throughput rates of up to 3 MSPS. Full details on the
AD7482 are found in the AD7482 data sheet (available from
Analog Devices, Inc.) and should be consulted in conjunction
with this data sheet when using the evaluation board.
On-board components include an AD780 (a pin programmable
2.5 V or 3 V ultra high precision band gap reference), AD829,
AD8022, and AD711 op amps, an ADM809 reset generator,
two 7S04 inverters and a 16-bit FCT245 type digital buffer.
Various link options are explained in detail in Table 1.
Interface to this board is accomplished 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.
