AD632ADZ

Overview

The AD632ADZ is a monolithic four-quadrant multiplier and divider manufactured by Analog Devices. It features internally trimmed precision with a maximum multiplying error of ±1.0% at +25°C. The device supports differential inputs for X, Y, and Z channels, offering high impedance and excellent common-mode rejection. It operates on dual supplies ranging from ±8V to ±18V, with rated performance at ±15V. The component provides a small signal bandwidth of 1 MHz and includes an adjustable scale factor up to ×10 gain. It is housed in a 14-lead side-brazed ceramic dual in-line package (D-14) suitable for industrial temperature ranges.

Feature Summary

• Internally trimmed monolithic construction ensuring high accuracy without external adjustments
• Fully differential high-impedance inputs for X, Y, and Z channels
• Adjustable scale factor providing variable gain capabilities up to ×10
• Low noise design with wideband noise specification of 90 µV rms

Applications

• High quality analog signal processing
• Differential ratio and percentage computations
• Algebraic and trigonometric function synthesis
• Accurate voltage controlled oscillators and filters

Procurement Notes

Verify the specific ordering suffix 'ADZ' corresponds to the RoHS compliant version of the 14-lead D-14 package when sourcing. Confirm that the required operating temperature range aligns with the -25°C to +85°C specification for this model variant. Ensure supply voltages remain within the ±8V to ±18V operational limits to maintain guaranteed performance specifications.

Selection Notes

Select the AD632ADZ when a four-quadrant multiplier with ±1.0% total error at room temperature is required. This model is appropriate for applications needing differential inputs and a 1 MHz bandwidth. Consider the D-14 ceramic package for through-hole mounting requirements. Evaluate if the internal trimming meets accuracy needs without additional calibration circuitry.

Part Context

The AD632 series serves as a pin-for-pin compatible replacement for the industry standard AD532, offering improved specifications. It integrates a stable reference and bias circuitry with thin film resistors and a buried zener reference for long-term stability. The device eliminates the need for separate instrumentation amplifiers in many configurations due to its high gain capability.

Replacement Considerations

The AD632ADZ is directly interchangeable with the AD632BDZ regarding form and fit. Both utilize the 14-lead D-14 package. Verify that the ±1.0% error tolerance of the ADZ variant meets the system requirements previously satisfied by other models in the family.
