AD632TD

Overview

The AD632TD is a monolithic four-quadrant multiplier and divider manufactured by Analog Devices Inc. It operates within a temperature range of -55°C to +125°C and utilizes a 14-lead side-brazed ceramic dual in-line package (D-14). The device features a transfer function defined as [(X1 − X2)(Y1 − Y2)/10] + Z2, with all inputs being differential and high impedance. It supports a maximum multiplying error of ±1.0% at +25°C and ±2.0% across the full operating temperature range. The unit requires a supply voltage between ±8 V and ±22 V, drawing a quiescent current of 4 mA to 6 mA.

Feature Summary

• Internally trimmed for precision performance without requiring external adjustments
• Supports variable gain up to ×10 through adjustable scale factors
• Features low noise design with excellent long-term stability

Applications

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

Procurement Notes

Verify that the specific order matches the required military screening standards if applicable. Confirm the package type corresponds to the D-14 ceramic variant. Ensure the supply voltage limits align with system requirements before integration. Check for RoHS compliance status based on the suffix designation.

Selection Notes

Select this component when extended industrial or military temperature ranges are necessary. The AD632TD offers higher accuracy than standard commercial variants while maintaining pin compatibility with legacy designs. Consider the differential input architecture for applications requiring high common-mode rejection ratios.

Part Context

This part belongs to the AD632 family of precision analog multipliers. It serves as an upgrade to older industry standards like the AD532, offering improved specifications and fully differential high-impedance Z inputs. The device integrates thin-film resistors and a buried zener reference for stable operation under adverse conditions.

Replacement Considerations

The AD632AD and AD632BD are compatible alternatives but operate within a narrower temperature range of -25°C to +85°C. Verify thermal requirements before substituting these commercial grade parts for the extended range AD632TD.
