GENERAL DESCRIPTION

regulator that acts as a supply to the on-board universal serial bus

controller, which interfaces to the AD5933. The user can power

the entire circuitry from the USB port of a computer. The eval-

uation board also has a high performance, trimmed, 16 MHz,

surface-mount crystal that can act as a system clock for the

AD5933, if required.

This document describes the evaluation board for the AD5933

and the application software developed to interface to the device.

The AD5933 is a high precision impedance converter system that

combines an on-board frequency generator with a 12-bit, 1 MSPS

ADC. The frequency generator allows an external complex im-

pedance to be excited with a known frequency. The response

signal from the impedance is sampled by the on-board ADC,

and the DFT is processed by an on-board DSP engine at each

excitation frequency. The AD5933 also contains an internal

temperature sensor with 13-bit resolution and operates from a

2.7 V to 5.5 V supply.

The various link options available on the evaluation board are

explained in Table 2. Interfacing to the AD5933 is through a

USB microcontroller, which generates the I²C signals necessary

to communicate with the AD5933.The user interfaces to the USB

microcontroller through a Visual Basic® graphic user interface

located on and run from the user PC. More information on the

AD5933 is available from Analog Devices, Inc., at www.analog.com

and should be consulted when using the evaluation board.

Other on-board components include an ADR423 3.0 V reference

that acts as a stable supply voltage for the separate analog and

digital sections of the device and an ADP3303 ultrahigh precision
