Converter, Network Analyzer

Data Sheet

AD5933

FEATURES

GENERAL DESCRIPTION

Programmable output peak-to-peak excitation voltage

to a maximum frequency of 100 kHz

Programmable frequency sweep capability with

serial I²C interface

Frequency resolution of 27 bits (<0.1 Hz)

Impedance measurement range from 1 kΩ to 10 MΩ

Capable of measuring of 100 Ω to 1 kΩ with additional

circuitry

The AD5933 is a high precision impedance converter system

solution that combines an on-board frequency generator with

a 12-bit, 1 MSPS, analog-to-digital converter (ADC). The

frequency generator allows an external complex impedance to

be excited with a known frequency. The response signal from

the impedance is sampled by the on-board ADC and a discrete

Fourier transform (DFT) is processed by an on-board DSP

engine. The DFT algorithm returns a real (R) and imaginary (I)

data-word at each output frequency.

Internal temperature sensor ( 2°C)

Internal system clock option

Once calibrated, the magnitude of the impedance and relative

phase of the impedance at each frequency point along the sweep

is easily calculated. This is done off chip using the real and

imaginary register contents, which can be read from the serial

I²C interface.

Phase measurement capability

System accuracy of 0.5%

2.7 V to 5.5 V power supply operation

Temperature range: −40°C to +125°C

16-lead SSOP package

Qualified for automotive applications

A similar device, also available from Analog Devices, Inc., is the

AD5934, a 2.7 V to 5.5 V, 250 kSPS, 12-bit impedance converter,

with an internal temperature sensor and is packaged in a 16-

lead SSOP.
