应用功能：Balanced Modulator/Demodulator The AD630 is a high precision balanced modulator which combinesa flexible commutating architecture with the accuracy andtemperature stability afforded by laser wafer trimmed thin-filmresistors. Its signal processing applications include balancedmodulation and demodulation, synchronous detection, phase detection, quadrature detection, phase sensitive detection,lock-in amplification and square wave multiplication.
