Overview

The AD630JNZ 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. The AD630JNZ can be thought of as a precision operational amplifier 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 used in precision signal processing and instrumentation applications that require wide dynamic range. When used as a synchronous demodulator in a lock-in amplifier configuration, the AD630JNZ can recover a small signal from 100dB of interfering noise (see the Lock-In Amplifier Applications section). Although optimized for operation up to 1kHz, the circuit is useful at frequencies up to several hundred kilohertz.
