Analog Devices Inc. AD532JD/+

Overview

AD532JD/+ from Analog Devices is an internally trimmed monolithic 4-quadrant analog multiplier IC with ±2.0% total multiplying error at 25°C, ±10 V output swing, and differential X/Y inputs supporting (X₁−X₂)(Y₁−Y₂)/10 V transfer function. It operates from ±10 V to ±18 V supplies, delivers 1 MHz small-signal bandwidth, and is housed in a hermetically sealed 14-lead side-brazed ceramic DIP (D-14) package for precision instrumentation signal processing.

For engineers reviewing the AD532JD/+ datasheet, AD532JD/+ pinout, AD532JD/+ application, or AD532JD/+ equivalent, this device serves as a drop-in replacement for legacy multipliers requiring external trim networks-enabling simplified algebraic computation, power measurement, and transducer-based instrumentation without external resistors or op amps.

Technical Context

The AD532JD/+ implements Gilbert-cell transconductance multiplication with laser-trimmed thin-film resistors on-die, enabling ratiometric scaling and eliminating external nulling components. Its differential X and Y input amplifiers provide 50 dB CMRR and high-impedance (10 MΩ) signal acquisition.

It supports four operating modes: multiplication with (X₁−X₂)(Y₁−Y₂)/10 V output; two-quadrant division via Z/(X₁−X₂) feedback configuration; one-quadrant square rooting with −10√Z output; and squaring with (X₁−X₂)²/10 V transfer function-all within a single monolithic die.

FAQ

What is the maximum multiplying error specification for AD532JD/+ at 25°C?

The AD532JD/+ has a guaranteed maximum multiplying error of ±2.0% at 25°C under rated conditions (±15 V supplies, −10 V ≤ X, Y ≤ +10 V). This value includes nonlinearity, feedthrough, and scale factor errors, and reflects the J-grade performance level defined in the AD532 Rev. F datasheet. The AD532JD/+ achieves this without external trimming components due to on-chip laser calibration.

Can AD532JD/+ operate with supply voltages other than ±15 V?

Yes, AD532JD/+ supports supply voltages from ±10 V to ±18 V. When operating outside ±15 V, input and output signal ranges must be scaled proportionally to avoid saturation-e.g., at ±12 V supplies, full-scale output is reduced to ±8 V. The device maintains specified performance including ±2.0% multiplying error and 1 MHz bandwidth across this range, as confirmed in the Power Supply Specifications table of the AD532 datasheet.

How is the VOS pin used in AD532JD/+ circuits?

The VOS pin on AD532JD/+ allows fine adjustment of output offset voltage using an external potentiometer. It is optional: if unused, VOS must be grounded to ensure stable operation. When active, VOS is trimmed with both X and Y inputs at 0 V to achieve zero output, or to null system-level offsets. This capability is retained in AD532JD/+ despite factory trimming, providing flexibility for high-precision applications where residual offset must be minimized below the typical ±30 mV spec.

Does AD532JD/+ support true 4-quadrant multiplication?

Yes, AD532JD/+ fully supports 4-quadrant multiplication via its differential X and Y inputs, implementing the transfer function (X₁−X₂)(Y₁−Y₂)/10 V. Both input pairs accept signals from −10 V to +10 V, enabling correct sign handling across all quadrants. This is verified in the Functional Block Diagram and Guaranteed Performance tables of the AD532 datasheet, and distinguishes AD532JD/+ from 2-quadrant multipliers that cannot process negative inputs on both axes simultaneously.

What package type is used for AD532JD/+ and why is it significant?

AD532JD/+ uses a 14-lead side-brazed ceramic dual in-line package (D-14), designated in the Ordering Guide as "D-14" with option code "DZ". This hermetic ceramic package provides superior moisture resistance, thermal stability, and long-term parameter retention compared to plastic DIPs-critical for industrial and aerospace applications where reliability over decades is required. Its θ_JA of 85°C/W also supports robust thermal management in dense PCB layouts.
