Analog Devices AD5934 Impedance Converter Datasheet
The AD5934 is a high‑precision 12‑bit impedance converter that combines an on‑board frequency generator with a 250 kSPS ADC. It offers programmable peak‑to‑peak excitation voltages, a 27‑bit frequency resolution, and a built‑in DSP for DFT processing, enabling accurate magnitude and phase measurements across a wide frequency range.
The device operates from 2.7 V to 5.5 V, supports an impedance range of 1 kΩ to 10 MΩ (with optional circuitry for 100 Ω‑1 kΩ), and provides up to 0.5 % total system accuracy. It is supplied in a 16‑lead SSOP package and includes detailed pin configurations, timing characteristics, and layout guidelines for optimal performance.
