Overview
The AD630ARZ-RL is a high precision balanced modulator/demodulator produced by Analog Devices Inc. It combines a flexible commutating architecture with the accuracy and temperature stability afforded by laser wafer trimmed thin film resistors. This component can be thought of as a precision op-amp with two independent differential input stages and a precision comparator that selects the active front end. The rapid response time of the comparator, coupled with the high slew rate and fast settling of the linear amplifiers, minimizes switching distortion. This makes the AD630ARZ-RL an ideal choice for applications requiring precisely fixed gain, switched gain, multiplexing, integrating-switching functions, and high speed precision amplification.
