PRODUCT DESCRIPTION
The AD630 is a high precision balanced modulator which bines a flexible mutating architecture with the accuracy and temperature stability afforded by laser wafer trimmed thin-film resistors. Its signal processing applications include balanced modulation and demodulation, synchronous detection, phase detection, quadrature detection, phase sensitive detection, lock-in amplification and square wave...
