AD630BDZ General Description

The AD630 is a high precision balanced modulator/demodulatorthat combines a flexible commutating architecture with theaccuracy and temperature stability afforded by laser wafer trimmedthin film resistors. A network of on-board applications resistorsprovides precision closed-loop gains of ±1 and ±2 with 0.05%accuracy (AD630B). These resistors may also be used to accuratelyconfigure multiplexer gains of 1, 2, 3, or 4. External feedbackenables high gain or complex switched feedback topologies.
