Product details
Overview
AD532KHZ from Analog Devices is an internally trimmed, monolithic 4-quadrant analog multiplier IC with ±1.0% maximum 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 signal conditioning and airborne navigation computation circuits.
For engineers reviewing the AD532KHZ datasheet, AD532KHZ pinout, AD532KHZ application, or AD532KHZ equivalent, this page delivers verified specifications, TO-100 metal-can package details, functional pin mapping, real-world use cases in power measurement and algebraic computation, and two validated alternative multipliers for design flexibility.
Technical Context
The AD532KHZ implements a laser-trimmed Gilbert-cell transconductance core to achieve ratiometric scaling and ±1.0% full-scale multiplication error without external trim networks. Its differential X and Y amplifiers provide 75 dB CMRR and high-impedance (10 MΩ) inputs, enabling noise-immune transducer signal processing.
It supports four operating modes: multiplication with (X₁−X₂)(Y₁−Y₂)/10 V transfer function; two-quadrant division via 10 V·Z/(X₁−X₂); one-quadrant square rooting with −10√V·Z; and squaring with (X₁−X₂)²/10 V - all within a single monolithic die operating on ±15 V supplies.
Key Specifications

Pinout & Package
AD532KHZ is housed in a hermetically sealed 10-pin TO-100 metal can package (H-10), suitable for high-reliability aerospace and military applications requiring thermal stability and EMI shielding.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Y1 | Positive input of Y differential pair - used with Y2 to reject common-mode interference |
| 2 | +VS | Positive supply terminal - must be decoupled locally for stable high-frequency operation |
| 3 | Z | Dual-purpose terminal: feedback node in multiply/square mode; signal input in divide/sqrt mode |
| 4 | OUT | Main analog output - low-impedance (1 Ω) buffered node capable of driving 1000 pF loads |
| 5 | −VS | Negative supply terminal - symmetric ±VS required for full ±10 V output swing |
| 6 | X1 | Positive input of X differential pair - paired with X2 for balanced signal injection |
| 7 | X2 | Negative input of X differential pair - completes differential X path and enables sign control |
| 8 | GND | Common reference - serves as signal return and substrate tie for internal circuitry |
| 9 | VOS | Output offset adjust - optional connection for fine nulling in precision DC-coupled systems |
| 10 | Y2 | Negative input of Y differential pair - enables true 4-quadrant operation and noise rejection |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPY100KG | ±0.5% max error, ±12 V output, requires external trim resistors for full accuracy | Higher precision but increased layout complexity and calibration effort | Choose when absolute best static accuracy outweighs design simplicity and production test burden |
| AD632AH | ±0.5% max error, 20 MHz bandwidth, TO-100 package, ±15 V only | Superior speed and accuracy but higher power consumption (12 mA vs. 6 mA) | Prefer for wideband modulation or RF signal processing where >1 MHz bandwidth is critical |
Compared with MPY100KG and AD632AH, the AD532KHZ offers optimal balance of ±1.0% accuracy, 1 MHz bandwidth, and zero-trim operation - making it ideal for cost-sensitive, high-reliability analog computation where ease of qualification and thermal stability are prioritized over ultimate speed or precision.

FAQ
What is the guaranteed multiplying accuracy of the AD532KHZ over temperature?
The AD532KHZ guarantees ±1.0% maximum 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-induced drift - all measured under standard ±15 V supply conditions with differential inputs driven within ±10 V limits. The AD532KHZ achieves this without external trim components due to on-die laser trimming.
Can the AD532KHZ operate from supply voltages other than ±15 V?
Yes, the AD532KHZ operates from ±10 V to ±18 V. At reduced supplies (e.g., ±12 V), output swing scales proportionally to maintain linearity, and input signal ranges must be adjusted accordingly to avoid saturation. Power supply rejection remains stable across this range due to internal ratiometric trimming - unlike older multipliers that degrade significantly outside nominal ±15 V rails.
How does the AD532KHZ support square root computation?
The AD532KHZ performs square root via its Z-input configured in feedback mode with output connected to both X and Y inputs, implementing −10√V·Z transfer function. It requires external diode D1 (as shown in Figure 17) to prevent latch-up near Z = 0 V. Total error is ±1.0% for 0 V ≤ Z ≤ 10 V, and VOS adjustment is performed with ZIN = +0.1 V to set VOUT = −1.0 V for calibration.
What is the purpose of the VOS pin on the AD532KHZ?
The VOS pin on the AD532KHZ provides optional fine adjustment of output offset voltage - useful in DC-coupled applications demanding sub-millivolt nulling. When unused, VOS must be grounded per datasheet requirement. In precision systems, it's trimmed with both X and Y inputs at 0 V to achieve zero output, compensating for residual laser-trim errors and temperature drift not covered by the ±1.0% spec.
Is the AD532KHZ pin-compatible with earlier AD532 variants like AD532JDZ?
No - the AD532KHZ uses the 10-pin TO-100 (H-10) metal can package, while AD532JDZ uses the 14-pin side-brazed ceramic DIP (D-14). Pin counts, layouts, and thermal characteristics differ significantly. Though both implement identical electrical functionality and share core specifications, PCB redesign and requalification are required when substituting between H-10 and D-14 packages.
