AD633ANZ

Overview

The AD633ANZ is a four-quadrant analog multiplier manufactured by Analog Devices, housed in an 8-lead PDIP package. It operates on dual supply voltages ranging from ±8V to ±18V with a typical supply current of 4mA. The device features a small-signal bandwidth of 1MHz and a slew rate of 20V/μs. It includes high-impedance differential X and Y inputs, a unity-gain summing input (Z), and provides a low-impedance output scaled by a laser-trimmed 10V reference. Total error is maintained within 2% of full scale across the industrial temperature range of -40°C to +85°C.

Feature Summary

• Laser-trimmed accuracy ensures total error remains within 2% of full scale without requiring external components.
• High-impedance differential X and Y inputs facilitate direct signal interfacing while minimizing loading effects.
• Integrated unity-gain summing input allows for flexible circuit configurations including gain adjustment and output addition.

Applications

• Multiplication, division, and squaring operations
• Modulation and demodulation circuits
• Phase detection systems
• Voltage-controlled amplifiers and attenuators

Procurement Notes

Verify the specific suffix ANZ confirms the PDIP-8 through-hole package and industrial temperature rating (-40°C to +85°C). Confirm RoHS compliance status as required by project specifications. Ensure power supply rails match the ±8V to ±18V operational limits. Validate pinout compatibility against existing PCB footprints before finalizing procurement orders.

Selection Notes

Select this component when a complete, low-cost analog multiplier solution is required without external scaling resistors. The integrated 10V reference simplifies design compared to discrete multiplier architectures. Consider the 1MHz bandwidth and 20V/μs slew rate for signal processing needs. Verify that the through-hole packaging aligns with assembly capabilities.

Part Context

The AD633 series represents a family of low-cost, four-quadrant analog multipliers designed for general-purpose signal processing. The AD633ANZ variant specifically denotes the industrial temperature grade packaged in a standard plastic dual in-line format. This part eliminates the need for complex external calibration networks typically found in older multiplier designs.
