250 kSPS, 12-Bit Impedance Converter, Network Analyzer

GENERAL DESCRIPTION The AD5934 is a high precision impedance converter system solution which combines an on-board frequency generator with a 12-bit, 250 kSPS, analog-to-digital converter (ADC). The frequency generator allows an external complex impedance to be excited with a known frequency. Th

250 kSPS、12位阻抗轉(zhuǎn)換器網(wǎng)絡(luò)分析儀

AD5934是一款高精度的阻抗轉(zhuǎn)換器系統(tǒng)解決方案，片上集成一個頻率發(fā)生器和一個12位、250 kSPS模數(shù)轉(zhuǎn)換器(ADC)。用頻率發(fā)生器產(chǎn)生的信號來激勵外部復(fù)阻抗，外部阻抗的響應(yīng)信號由片上ADC進(jìn)行采樣，然后由片上DSP進(jìn)行離散傅里葉變換(DFT)處理。DFT算法在每個頻率上返回一個實部(R)數(shù)據(jù)字和一個虛部(I)數(shù)據(jù)字。\n\n 校準(zhǔn)后，使用以下兩個公式很容易算出各掃描頻率點的阻抗幅度和相應(yīng)的阻抗相位：\n\n 幅度 = √ R2 + I2相位 = Tan-1 (I/R)\n\n ADI公司還提供一款類似器件AD5933，它是一款2.7 V至5.5 V、1 MS ? 可編程輸出峰峰值激勵電壓，輸出頻率最高達(dá)100 kHz \n\n? 可編程頻率掃描功能和串行I2C接口 \n\n? 頻率分辨率：27位(<0.1 Hz) \n\n? 阻抗測量范圍：1 kΩ至10 MΩ \n\n? 利用附加電路可測量100 Ω至1 kΩ阻抗;
