AD630ADZ

AD630 is a high precision balanced modulator/demodulator that combines a flexible commutating architecture with the accuracy and temperature stability afforded by laser wafer trimmed thin film resistors. These resistors may also be used to accurately configure multiplexer gains of 1, 2, 3, or 4. External feedback enables high gain or complex switched feedback topologies. It can be thought of as a precision op-amp with two independent differential input stages and a precision comparator that is used to select the active front end. The rapid response time of this comparator coupled with the high slew rate and fast settling of the linear amplifiers minimize switching distortion. It is widely used in applications such as balanced modulation and demodulation, synchronous detection, phase detection, quadrature detection, phase sensitive detection, lock in amplification, square wave multiplication etc.
