AD630ARZ-RL

• Balanced Modulator / Demodulator Function
• DC to 2 MHz Maximum Frequency Range
• 350 K Hz Frequency Parameter per the Attribute Record
• Wide-Body SOIC Surface-Mount package, Tin Contact Plating
• Tape and Reel packaging; RoHS Compliant
• Manufacturer Lifecycle Status: NRND - Not Recommended for New Designs

The Analog Devices AD630ARZ-RL is a balanced modulator/demodulator covering DC to 2 MHz, with a 350 k Hz frequency figure listed in the attribute record. It is supplied in a wide-body SOIC surface-mount package with tin contact plating, on tape and reel, and is RoHS compliant. Note that Analog Devices lists this part as NRND (not recommended for new designs), so AD630ARZ-RL should be treated as a sustaining or last-time-buy item rather than a new-design selection.

A balanced modulator/demodulator is the core of a lock-in amplifier: it multiplies an incoming signal by a reference at the same frequency, so only signal energy coherent with the reference survives the following low-pass filter. That lets a measurement recover microvolt-level signals buried well below the noise floor. Typical applications are lock-in amplifiers and synchronous detectors, precision AC bridge and impedance measurement, phase detection, square-wave multiplication, and sensor excitation and readout in scientific instrumentation. Buyers are test-and-measurement and scientific instrument makers, often sourcing for existing platforms given the NRND status.
