Analog Devices AD633JRZ-R7 Analog Multiplier
Analog Devices AD633JRZ-R7 Product Overview
The AD633JRZ-R7 is a functionally complete four-quadrant analog multiplier from Analog Devices, featuring high-impedance differential X and Y inputs and a high-impedance summing input (Z). Housed in a compact 8-lead SOIC package, it is designed for applications requiring multiplication, division, squaring, modulation/demodulation, and phase detection.
The device includes 3 amplifiers, operates over a 1 MHz small-signal bandwidth, and delivers a 20 V/µs slew rate. It is laser-trimmed to a guaranteed total accuracy of 2% of full scale and features a 10 V nominal full-scale output voltage from an embedded Zener reference. Supply voltage range is ±8 V to ±18 V. Operating temperature range is 0 °C to +70 °C (commercial grade).

Analog Devices AD633JRZ-R7 Key Advantages
The AD633JRZ-R7 delivers four-quadrant multiplication with 1 MHz bandwidth and 20 V/µs slew rate in a cost-effective 8-lead SOIC package. It is complete and requires no external components, simplifying design and reducing BOM. Laser-trimmed accuracy ensures 2% full-scale total error and stable performance over temperature and supply variations. The high-impedance inputs (10 MΩ) minimize signal source loading, while the Z input provides access to the output buffer for summing multiple multipliers or configuring gain and current outputs.
Analog Devices AD633JRZ-R7 Typical Applications
Multiplication, division, and squaring circuits
Modulation and demodulation systems
Phase detection and lock-in amplification
Voltage-controlled amplifiers, attenuators, and filters
Active power measurement and RMS-to-DC conversion
Automatic gain control (AGC) and signal conditioning
Why Choose the Analog Devices AD633JRZ-R7?
