AD632TD/883B

Overview

The AD632TD/883B is an internally trimmed 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 maximum multiplying error of ±0.5% without external trims, a small signal bandwidth of 1 MHz, and a slew rate of 20 V/µs. It supports differential inputs for X, Y, and Z channels with a transfer function of [(X1 − X2)(Y1 − Y2)/10] + Z2.

Feature Summary

• Internally trimmed to ensure a maximum four-quadrant error of ±0.5% without requiring external adjustments.
• Features fully differential, high-impedance inputs for X, Y, and Z channels to support complex algebraic computations.
• Provides adjustable scale factors capable of delivering up to ×10 gain, reducing the need for separate instrumentation amplifiers.

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 that the specific part number AD632TD/883B corresponds to the military-grade screening requirements defined in MIL-STD-883 Level B. Confirm package integrity for the 14-lead ceramic dual in-line configuration prior to integration. Ensure supply chain documentation matches the manufacturer's ordering guide specifications for extended temperature operation.

Selection Notes

Select this component when precise four-quadrant multiplication or division is required over an extended industrial or military temperature range. The internal trimming eliminates the need for manual calibration circuits. Consider the differential input architecture if common-mode rejection is critical for the application environment.

Part Context

This component belongs to the AD632 series of precision analog multipliers. It serves as a pin-for-pin compatible upgrade to the industry-standard AD532, offering improved specifications such as lower noise and higher accuracy. The series includes variants optimized for different temperature ranges and packaging styles.
