AD630JNZ

Experience unparalleled performance and reliability with the AD630JNZ, a high precision balanced modulator/demodulator designed for a wide range of applications. Its flexible commutating architecture and laser-wafer trimmed thin film resistors ensure exceptional accuracy and temperature stability, setting it apart from traditional solutions. The onboard applications resistors provide precise closed-loop gains of ±1 and ±2, with a remarkable accuracy of 0.05% for the AD630B variant. These resistors can be easily configured for multiplexer gains of 1, 2, 3, or 4, allowing for customizable setups tailored to specific needs. Incorporating external feedback further enhances the device's versatility, enabling users to achieve high gain outputs or implement sophisticated switched feedback topologies with ease
