Analog Devices Inc. AD532JHZ

Overview

AD532JHZ from Analog Devices is an internally trimmed monolithic 4-quadrant analog multiplier IC with differential X and Y inputs, ±2% full-scale multiplying error at 25°C, ±10 V output swing, and guaranteed operation from 0°C to 70°C in a hermetically sealed TO-100 metal can package. It implements the transfer function (X₁ − X₂)(Y₁ − Y₂)/10 V for precision multiplication, division, squaring, and square rooting in instrumentation signal chains.

For engineers reviewing the AD532JHZ datasheet, AD532JHZ pinout, AD532JHZ application, or AD532JHZ equivalent, this device serves as a drop-in replacement for legacy multipliers requiring external trim networks-offering simplified layout, improved power supply rejection (±0.05 %/%), and high CMRR (50 dB) without external components.

Technical Context

The AD532JHZ uses laser-trimmed thin-film resistors on-die to achieve ratiometric scaling and eliminate external nulling networks. Its Gilbert-cell multiplier core delivers 1 MHz small-signal bandwidth and 45 V/μs slew rate, enabling real-time analog computation in feedback loops and modulation circuits.

Differential X and Y inputs provide noise immunity and algebraic flexibility: configurations support XY/10 V multiplication, 10 V·Z/(X₁−X₂) division, ±√(10 V·Z) square rooting, and (X₁−X₂)²/10 V squaring-all within a single monolithic die with no external op amp required.

Key Specifications

Pinout & Package

AD532JHZ is housed in a hermetically sealed 10-pin TO-100 metal can package (H-10A), optimized for high-reliability instrumentation and aerospace environments. Thermal resistance θ_JA = 150°C/W enables stable operation without forced cooling in ambient temperatures up to 70°C.

FAQ

What is the maximum multiplying error specification for AD532JHZ at 25°C?

The AD532JHZ has a guaranteed maximum multiplying error of ±2.0% of full scale at 25°C, as specified in Table 1 of the Rev. F datasheet. This error includes contributions from X and Y input nonlinearities, feedback and scale factor errors, and is measured across the full ±10 V input range with ±15 V supplies. The AD532JHZ maintains this specification over its rated 0°C to 70°C operating temperature range.

Can AD532JHZ operate with supply voltages other than ±15 V?

Yes, AD532JHZ supports supply voltages from ±10 V to ±18 V per the Power Supply Specifications table. Operation at ±12 V is fully supported, though input and output signal ranges must be scaled proportionally to avoid saturation - for example, at ±12 V supplies, the usable output swing reduces to approximately ±8 V. The device's ±0.05 %/% supply rejection ensures minimal error contribution from supply variation within this range.

How is the VOS pin used in AD532JHZ, and is it required?

The VOS pin on AD532JHZ provides optional fine adjustment of output offset voltage. It is factory trimmed for zero output when both X and Y inputs are zero, so grounding VOS is sufficient for most applications. Only in high-precision systems requiring sub-10 mV residual offset should VOS be actively adjusted using an external potentiometer - typically during final system calibration. Leaving VOS unconnected is not recommended; it must be grounded if unused to preserve factory trim integrity.

What package type does AD532JHZ use, and what are its thermal characteristics?

AD532JHZ is packaged in a hermetically sealed 10-pin TO-100 metal can (H-10A package), with thermal resistance θ_JA = 150°C/W and θ_JC = 25°C/W. This package provides superior moisture and particle ingress protection compared to plastic DIPs, making it suitable for high-reliability military, aerospace, and industrial environments. The metal can also acts as a shield against EMI, enhancing noise immunity in sensitive analog signal paths.

Does AD532JHZ support division and square root functions, and how are they configured?

Yes, AD532JHZ supports two-quadrant division using the transfer function 10 V·Z/(X₁−X₂) and one-quadrant square rooting with ±√(10 V·Z). Division requires connecting Z as the numerator input and configuring the X inputs to form the denominator (X₁−X₂); square rooting connects Z to the output and uses diode protection to prevent latch-up near zero. Both modes leverage the same internal multiplier cell and op amp, with error scaling directly tied to the denominator magnitude - detailed connection diagrams are provided in Figures 16 and 17 of the datasheet.
