EVAL-AD7492CB

FEATURES

Interfacing to this board is through a 96-way connector. This

96-way connector is compatible with the EVAL-CONTROL

BRD2 which is also available from Analog Devices. External

sockets are provided for the CONVST input and the VIN

inputs.

PC Software for Control and Data Analysis when used

with EVAL-CONTROL BRD2

When using this evaluation board with the EVAL-CON-

TROL BRD2, all supplies are provided from the EVAL-

CONTROL BRD2 through the 96 way connector.

When using the board as a stand alone unit, external supplies

must be provided. This evaluation board has five power

supply inputs: V_DD, A_GND, V_SS, V_DRIVEand D_GND. +5 V must

be connected to the V_DDinput to supply the AV_DDand DV_DD

pins on the AD7492, the AD780 voltage reference, the

positive supply pin of all three op-amps and the digital

control logic. 0 V is connected to the A_GNDinput. -5 V must

be connected to the V_SSinput to supply the negative supply

pins on all three op-amps. The V_DRIVEinput can be used to

provide an external voltage for the output drivers on the

AD7492. If an external V_DRIVEis supplied, it is referenced to

the D_GNDinput which should be tied to 0 V. The supplies are

decoupled to the relevant ground plane with 47µF tantalum

and 0.1µF multilayer ceramic capacitors at the point where

they enter the board. The supply pins of the op-amps and

INTRODUCTION

This Technical Note describes the evaluation board for the

AD7492 12-bit, high speed, low power, internal reference

and clock, successive approximation A/D converter that

operates from a single 2.7 V to 5.25 V supply. Full data on

the AD7492 is available in the AD7492 data sheet available

from Analog Devices and should be consulted in conjunction

with this Technical Note when using the Evaluation Board.

On-board components include an AD780 which is a pin

programmable +2.5 V or +3 V ultra high precision bandgap

reference, two AD797 op-amps used to buffer the analog

input, and an OP07 op-amp used to buffer the DC bias

voltage applied to the optional analog input bias-up circuit.

There are various link options which are explained in detail

on page 2.
