Product details
Overview
AD632TH/883B from Analog Devices is a precision monolithic four-quadrant analog multiplier/divider with differential high-impedance X, Y, and Z inputs, ±0.5% maximum multiplying error at +25°C, 1 MHz small-signal bandwidth, and operation over −55°C to +125°C for aerospace and military applications requiring stable analog computation.
For engineers reviewing the AD632TH/883B datasheet, AD632TH/883B pinout, AD632TH/883B application, or AD632TH/883B equivalent, this page delivers verified specifications, TO-100 metal-can package details, functional block context, real-world use cases in ratio computation and VCO design, and two validated alternative parts with documented differences.
Technical Context
The AD632TH/883B implements a [(X₁−X₂)(Y₁−Y₂)/10] + Z₂ transfer function using translinear multiplier elements and a high-gain output amplifier. Its fully differential architecture supports floating numerator/denominator division and algebraic synthesis without external trims.
It features on-chip thin-film resistors and buried zener reference for long-term stability, 90 µV rms wideband noise (10 Hz–10 kHz), and ±11 V output swing into 2 kΩ load - all guaranteed under MIL-STD-883B screening for extended temperature operation.
Key Specifications

Pinout & Package
AD632TH/883B uses the hermetically sealed 10-pin TO-100 metal can package (H-10), rated for high-reliability military applications with low thermal resistance (θJA = 150°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Y1) | Y multiplicand noninverting input | Differential Y-path entry; used with Y2 for balanced signal injection and feedthrough suppression. |
| 2 (+VS) | Positive supply voltage | Accepts +8 V to +22 V; powers internal amplifiers and reference circuitry. |
| 3 (Z1) | Z summing node noninverting input | Injects offset or correction signal directly into output stage with unity gain and high impedance. |
| 4 (OUT) | Product output | Low-impedance (0.1 Ω), ±11 V swing output capable of driving 2 kΩ loads. |
| 5 (−VS) | Negative supply voltage | Accepts −8 V to −22 V; complements +VS for dual-supply operation. |
| 6 (X1) | X multiplicand noninverting input | Differential X-path entry; paired with X2 for common-mode rejection up to 90 dB. |
| 7 (X2) | X multiplicand inverting input | Completes X differential pair; enables true four-quadrant multiplication with polarity inversion. |
| 8 (Z2) | Z summing node inverting input | Reference point for Z-input; tied to system ground or bias network to set summing baseline. |
| 9 (VOS) | Offset voltage adjustment | Allows fine-tuning of output DC offset via external potentiometer (±30 mV trim range). |
| 10 (Y2) | Y multiplicand inverting input | Completes Y differential pair; critical for minimizing Y-channel AC feedthrough below 0.01%. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD632SH/883B | Same TO-100 package and −55°C to +125°C rating, but ±1.0% max multiplying error (vs. ±0.5% for AD632TH/883B). | Acceptable where tighter error budget is not required, e.g., non-critical telemetry scaling. | Select AD632SH/883B only if cost sensitivity outweighs accuracy requirements. |
| AD632TD/883B | SBDIP ceramic D-14 package instead of TO-100; identical electrical specs and MIL-STD-883B screening. | Preferred for PCB assembly compatibility with surface-mount processes or higher pin-count routing density. | Choose AD632TD/883B when board layout constraints favor 14-lead SBDIP over 10-pin metal can. |
Compared with AD632TH/883B, AD632SH/883B trades 0.5% absolute error margin for lower unit cost, while AD632TD/883B preserves identical performance in a different package form factor - neither is pin-compatible, but both share the same functional interface and qualification level.

FAQ
What is the guaranteed multiplying error specification for AD632TH/883B over its full operating temperature range?
The AD632TH/883B guarantees ±1.0% maximum multiplying error over the full −55°C to +125°C range. At +25°C, the error is tightened to ±0.5% maximum, as confirmed in the Rev. D datasheet Table 1 under AD632T specifications. This performance is validated per MIL-STD-883B screening.
Does AD632TH/883B support true four-quadrant multiplication, and how is it implemented?
Yes, AD632TH/883B supports true four-quadrant multiplication via fully differential X1/X2 and Y1/Y2 inputs. The transfer function [(X₁−X₂)(Y₁−Y₂)/10] + Z₂ inherently handles all sign combinations, enabling accurate computation of signed products without external polarity logic or switching networks.
What package type and sealing method does AD632TH/883B use, and why is it significant for military applications?
AD632TH/883B uses the 10-pin TO-100 metal can package with hermetic sealing. This construction prevents moisture ingress and provides superior mechanical robustness and thermal conductivity - essential for reliability in vibration-prone, high-humidity, or vacuum environments typical of aerospace and defense platforms.
Can AD632TH/883B be used as a precision divider, and what is its accuracy in that mode?
Yes, AD632TH/883B operates as a precision divider with transfer function [10(Z₁−Z₂)/(X₁−X₂)] + Y₁. For X = 10 V and −10 V ≤ Z ≤ +10 V, total error is ±0.75% maximum; for X = 1 V and −1 V ≤ Z ≤ +1 V, error is ±2.0% maximum - both specified over −55°C to +125°C per datasheet Table 1.
How does the VOS pin function in AD632TH/883B, and what is its adjustment range?
The VOS pin on AD632TH/883B allows external trimming of output DC offset voltage. A ±30 mV adjustment range is supported using a 10 kΩ potentiometer between pins 2 (+VS) and 5 (−VS), with the wiper connected to VOS. This enables final system-level calibration after PCB assembly and thermal stabilization.
