AD632AHZ

Overview

The AD632AHZ is a monolithic four-quadrant multiplier and divider manufactured by Analog Devices. It features an internally trimmed architecture with a maximum multiplying error of ±0.5% at +25°C. The device operates on dual power supplies ranging from ±8 V to ±18 V, consuming a typical quiescent current of 4 mA. It provides a small-signal bandwidth of 1 MHz and supports gains up to ×10 via scale-factor adjustment. The component utilizes a hermetically sealed 10-pin metal header (TO-100) package.

Feature Summary

• Internally trimmed for high precision with minimal external calibration requirements
• Four-quadrant analog multiplication and division capabilities
• High impedance differential inputs for X, Y, and Z signals
• Adjustable scale factor providing variable gain functionality

Applications

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

Procurement Notes

Verify the specific suffix 'HZ' corresponds to the RoHS-compliant 10-pin metal header package variant. Confirm that the required operating temperature range aligns with the -25°C to +85°C specification. Ensure supply voltages remain within the ±8 V to ±18 V limits to maintain guaranteed performance levels.

Selection Notes

Select this model when high accuracy is required without external trimming adjustments. The TO-100 package is suitable for applications requiring hermetic sealing. Consider the ±0.5% total error specification against system tolerance requirements. Evaluate the 1 MHz bandwidth against signal frequency needs.

Part Context

This component belongs to the AD632 family of precision analog multipliers. It serves as a pin-for-pin compatible upgrade to the industry-standard AD532, offering improved specifications such as fully differential high-impedance Z inputs. The family includes variants with extended temperature ranges and MIL-STD-883 screening options.

Replacement Considerations

The AD632ADZ is a direct pin-compatible alternative in a ceramic DIP package. For extended temperature operations, the AD632SH or AD632TH series are available. Verify package dimensions and thermal characteristics when substituting.
