1 MSPS, 12-Bit Impedance  
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.
