Analog Devices Inc. AD532KD/+

Overview

AD532KD/+ from Analog Devices is an internally trimmed monolithic 4-quadrant analog multiplier IC with guaranteed ±1.0% total multiplying error at 25°C, ±10 V output swing, and differential X/Y inputs supporting (X₁−X₂)(Y₁−Y₂)/10 V transfer function - used in precision instrumentation for power measurement and algebraic computation.

For engineers reviewing the AD532KD/+ datasheet, AD532KD/+ pinout, AD532KD/+ application, or AD532KD/+ equivalent, this page delivers verified specifications, functional context, package mapping, real-world use cases, and validated alternative options for analog signal processing design.

Technical Context

The AD532KD/+ implements a laser-trimmed Gilbert-cell transconductance multiplier core with integrated high-impedance differential input amplifiers and a feedback-output op amp, enabling self-contained multiplication, division, squaring, and square-rooting without external trim networks.

It operates over 0°C to +70°C with ±15 V supply (±10 V to ±18 V range), delivers 1 MHz small-signal bandwidth, 45 V/μs slew rate, and achieves 75 dB common-mode rejection on both X and Y differential inputs - critical for noise-immune transducer signal conditioning.

Key Specifications

Pinout & Package

AD532KD/+ is supplied in a hermetically sealed 14-lead side-brazed ceramic DIP (D-14) package, rated for 0°C to +70°C operation, with 85°C/W junction-to-ambient thermal resistance.

FAQ

What is the guaranteed multiplying accuracy of the AD532KD/+ over temperature?

The AD532KD/+ guarantees ±1.0% total multiplying error at 25°C and ±1.5% over its full 0°C to +70°C operating range. This specification includes contributions from nonlinearity, feedthrough, and temperature drift - all measured per Analog Devices Rev. F datasheet Table 1. The AD532KD/+ does not require external trimming to meet this spec, unlike earlier multiplier ICs.

Can the AD532KD/+ operate with supply voltages other than ±15 V?

Yes, the AD532KD/+ supports supply voltages from ±10 V to ±18 V while maintaining specified performance. At reduced rails (e.g., ±12 V), output swing scales proportionally to ±8 V, and input signal ranges must be adjusted accordingly to avoid saturation. Power supply rejection remains stable across this range due to on-chip trimming.

How is the VOS pin used in the AD532KD/+?

The VOS pin on the AD532KD/+ provides optional fine adjustment of output offset voltage. It is factory trimmed for zero error; grounding VOS maintains this calibration. If system-level offsets require correction, VOS is adjusted with X₁ = X₂ = 0 V and Y₁ = Y₂ = 0 V until OUT = 0 V. Unused, VOS must be grounded - floating it degrades accuracy.

Does the AD532KD/+ support true 4-quadrant multiplication?

Yes, the AD532KD/+ supports full 4-quadrant multiplication via its differential (X₁−X₂) and (Y₁−Y₂) inputs, enabling correct sign handling for all combinations of positive/negative input voltages. Its transfer function (X₁−X₂)(Y₁−Y₂)/10 V produces mathematically accurate signed products - essential for algebraic computation and vector operations.

What package type is used for the AD532KD/+?

The AD532KD/+ is supplied in a 14-lead side-brazed ceramic dual in-line package (D-14), also referenced as SBDIP. This hermetically sealed package provides high reliability, low leakage, and stable electrical performance across temperature - confirmed in the Analog Devices ordering guide and outline drawing H-10/D-14 documentation.
