Description

The AD630KNZ is a high precision balanced modulator that combines a flexible commutating 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 multiplication. A network of on-board applications resistors provides precision closed-loop gains of ±1 and ±2 with 0.05% accuracy (AD630B). These resistors may also be used to accurately configure multiplexer gains of +1, +2, +3, or +4. Alternatively, external feedback may be employed, allowing the designer to implement high gain or complex switched feedback topologies. The AD630KNZ 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. In addition, the AD630 has extremely low crosstalk between channels of –100 dB @ 10 kHz.
