Product details
Overview
AD532SD/883B from Analog Devices is an internally laser-trimmed monolithic four-quadrant analog multiplier/divider IC with guaranteed ±1.0% multiplying error at 25°C and ±4.0% over −55°C to +125°C, ±10 V output swing, and differential (X1−X2)(Y1−Y2)/10 V transfer function - used in precision airborne navigation computation, power measurement instrumentation, and high-reliability military signal processing systems.
For engineers reviewing the AD532SD/883B datasheet, AD532SD/883B pinout, AD532SD/883B application, or AD532SD/883B equivalent, this device delivers verified ratiometric trimming, 75 dB common-mode rejection, 1 MHz small-signal bandwidth, and direct replacement capability for legacy hybrid multipliers requiring external trim networks - critical for aerospace-grade analog computation where layout stability and temperature-invariant gain are mandatory.
Technical Context
The AD532SD/883B implements Gilbert-cell transconductance multiplication with on-chip laser-trimmed thin-film resistors, enabling true ratiometric scaling and eliminating external nulling components. Its differential X and Y inputs support noise-immune transducer interfacing while maintaining ±10 V input range and 10 MΩ differential resistance.
It operates in four modes: multiplication ((X1−X2)(Y1−Y2)/10 V), two-quadrant division (10 V·Z/(X1−X2)), one-quadrant square rooting (±√(10 V·Z)), and squaring ((X1−X2)²/10 V), all with guaranteed error bounds across its full military temperature range and qualified per MIL-STD-883 Class B.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
AD532SD/883B is housed in a hermetically sealed 14-lead side-brazed ceramic DIP (D-14 package), rated for extended military temperature operation and qualified per MIL-STD-883B. This package provides low thermal resistance (θJC = 22°C/W), high reliability under thermal cycling, and immunity to moisture ingress in sealed chassis.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Z Input | Dual-purpose terminal: used as input in divider/square-root modes; tied to OUT in multiplier/squarer configurations. |
| 2 | OUT | Low-impedance (1 Ω) buffered product output; drives ≥2 kΩ loads with ±10 V swing and 45 V/μs slew rate. |
| 3 | −VS | Negative supply connection; supports −10 V to −22 V rails; referenced for internal bias and op amp feedback. |
| 4, 5, 6, 8 | NC | No internal connection; must remain unconnected to avoid parasitic coupling or mechanical stress on die bond wires. |
| 7 | X1 | Noninverting X multiplicand input; forms differential pair with X2 for CMRR-enhanced signal acquisition. |
| 9 | X2 | Inverting X multiplicand input; enables true differential subtraction (X1 − X2) with 10 MΩ input resistance. |
| 10 | GND | Analog common reference; must be star-connected to minimize ground-loop errors in precision instrumentation. |
| 11 | VOS | Output offset adjust terminal; used only when sub-mV nulling is required; otherwise grounded per MIL-STD-883B test flow. |
| 12 | Y2 | Inverting Y multiplicand input; completes differential Y-path (Y1 − Y2); matched to X2 for balanced CMRR. |
| 13 | Y1 | Noninverting Y multiplicand input; accepts ±10 V signals with <0.3% nonlinearity and <80 mV feedthrough. |
| 14 | +VS | Positive supply connection; supports +10 V to +22 V rails; powers internal op amp and multiplier cell core. |
Key Features
| Feature | Design Value |
|---|---|
| Laser-trimmed ratiometric scaling | Eliminates external trim resistors and improves PSRR by 3–40× vs. conventionally trimmed multipliers. |
| Differential X/Y inputs with 75 dB CMRR | Enables direct connection to Wheatstone bridges and isolated sensor outputs without external instrumentation amps. |
| Four operating modes in single IC | Reduces BOM count and PCB area versus discrete op-amp + multiplier solutions for navigation and test equipment. |
| MIL-STD-883B qualified D-14 package | Ensures mechanical robustness, hermeticity, and long-term parameter stability in vibration-prone aerospace platforms. |
| Self-contained operation | Requires no external op amp or feedback network - simplifies design verification and reduces failure modes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD534SD/883B | Higher accuracy (±0.5% max), wider bandwidth (10 MHz), but requires external trim resistors and ±15 V only. | Better for high-frequency modulation; unsuitable where board space or supply flexibility is constrained. | Select AD534SD/883B only when >1 MHz bandwidth and <±0.5% error are mandatory and external trimming is acceptable. |
| MPY100KG | Single-supply operation (0 to +15 V), lower cost, but ±2% error, no MIL-STD-883B qualification, and no Z-input square-root mode. | Applicable in commercial test gear; lacks radiation tolerance, hermetic packaging, and military temp range. | Choose MPY100KG only for non-critical benchtop instruments where cost and single-rail operation outweigh reliability needs. |
Compared with AD534SD/883B and MPY100KG, the AD532SD/883B uniquely combines MIL-qualified D-14 packaging, self-contained operation, and guaranteed ±4.0% error over −55°C to +125°C - making it the sole option for embedded analog computation in launch vehicle telemetry and hardened UAV flight controllers.

FAQ
What is the guaranteed multiplying error specification for AD532SD/883B over its full temperature range?
The AD532SD/883B guarantees a maximum multiplying error of ±4.0% of full scale over the extended operating temperature range of −55°C to +125°C, as verified per MIL-STD-883B Method 5005. This specification includes contributions from nonlinearity, feedthrough, and temperature-induced drift - all measured with ±15 V supplies and 2 kΩ load. The AD532SD/883B achieves this without external trimming components due to on-die laser trimming.
Does AD532SD/883B support true four-quadrant multiplication, and how is it implemented?
Yes, AD532SD/883B supports true four-quadrant multiplication via its differential (X1−X2)(Y1−Y2)/10 V transfer function, where both X and Y inputs accept ±10 V signals independently. This architecture allows signed product generation - e.g., negative × negative = positive - essential for vector math in navigation systems. The differential inputs are internally matched and laser-trimmed to ensure symmetry and minimize quadrant-dependent errors.
Can AD532SD/883B be used as a square rooter, and what is its accuracy in that mode?
Yes, AD532SD/883B operates as a one-quadrant square rooter with transfer function ±√(10 V·Z), achieving ±1.0% total error for 0 V ≤ Z ≤ 10 V at 25°C and ±1.5% over −55°C to +125°C. The circuit requires external diode D1 (as shown in Figure 17 of the datasheet) to prevent latch-up near Z = 0 V. Output offset is adjusted at ZIN = +0.1 V to yield VOUT = −1.0 V, ensuring monotonic response across the full range.
What is the purpose of the VOS pin on AD532SD/883B, and when must it be used?
The VOS pin on AD532SD/883B provides fine adjustment of output offset voltage, typically used in high-accuracy applications where residual ±30 mV factory-trimmed offset must be reduced further. It is optional: if unused, VOS must be grounded per MIL-STD-883B test requirements. When active, VOS is trimmed with Z = 0 V and (X1−X2) at full scale to null system-level offsets - critical for DC-coupled instrumentation chains.
Is AD532SD/883B pin-compatible with earlier AD532 variants like AD532KDZ?
Yes, AD532SD/883B shares identical pinout, footprint, and electrical interface with AD532JDZ and AD532KDZ in the D-14 package - confirmed by Analog Devices' Ordering Guide and Pin Configuration tables. However, AD532SD/883B adds MIL-STD-883B screening, extended temperature rating (−55°C to +125°C), and tighter error bounds over temperature, making it a drop-in replacement for legacy designs requiring enhanced reliability.
