ADI AD630BD

调制器/解调器0Hz ~ 2MHz通用

Overview

 The AD630BD 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. 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. External feedback enables high gain or complex switched feedback topologies.

 5. Laser trimming of the comparator and amplifying channel offsets eliminate the need for external nulling in most cases.
