Product details
Overview
AD632TD/883B from Analog Devices is a hermetically sealed, MIL-STD-883B-screened, four-quadrant precision analog multiplier/divider in a 14-lead side-brazed ceramic DIP (D-14) package. It delivers ±0.5% maximum multiplying error at +25°C, supports differential X/Y/Z inputs with [(X₁−X₂)(Y₁−Y₂)/10] + Z₂ transfer function, and operates across −55°C to +125°C for aerospace and defense signal processing.
For engineers reviewing the AD632TD/883B datasheet, AD632TD/883B pinout, AD632TD/883B application, or AD632TD/883B equivalent, this page provides verified specifications, military-grade screening confirmation, TO-100 vs. D-14 package distinction, Z-input summing capability, and direct comparison against AD532 and AD632TH/883B for high-reliability analog computation.
Technical Context
The AD632TD/883B implements a translinear multiplier core with buried zener reference and thin-film resistor network, enabling guaranteed ±0.5% multiplying error over full military temperature range without external trims. Its fully differential Z input accepts summing signals up to ±10 V, and internal 10× scaling factor is adjustable down to 3 V via external resistor.
It achieves 1 MHz small-signal bandwidth, 20 V/µs slew rate, and 90 µV rms wideband noise (10 Hz–10 kHz), supporting accurate voltage-controlled oscillators, ratio computations, and trigonometric synthesis. The device is pin-compatible with AD532 but adds differential Z input and eliminates need for external instrumentation amplifiers in preconditioning paths.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision analog multiplier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD632TH/883B | Same electrical specs and MIL-STD-883B screening, but in 10-pin TO-100 metal can package - higher thermal resistance (θJA = 150°C/W vs. 95°C/W) | Preferred for ultra-high-reliability chassis-mount or vacuum environments where metal-can hermeticity exceeds ceramic DIP robustness | Select AD632TH/883B when board space allows larger footprint and thermal design prioritizes package-level hermeticity over PCB-level heat dissipation |
| AD532KD | Legacy industry-standard multiplier; ±1% multiplying error, no differential Z input, no MIL-STD-883B option; requires external trim for <0.5% accuracy | Suitable for commercial test equipment or non-military embedded systems where cost and legacy compatibility outweigh precision and screening needs | Choose AD532KD only if redesign is constrained by existing AD532-based layouts and ±1% error is acceptable under worst-case temperature |
Compared with AD632TH/883B, AD632TD/883B offers superior thermal performance in PCB-mounted applications due to lower θJA, while AD532KD lacks both the differential Z architecture and military screening - making AD632TD/883B the sole choice for new high-reliability analog computing designs requiring guaranteed ±0.5% error and full MIL-STD-883B compliance.

FAQ
What is the guaranteed multiplying error specification for AD632TD/883B over its full operating temperature range?
The AD632TD/883B guarantees ±1.0% maximum multiplying error over the full −55°C to +125°C military temperature range. At +25°C, the error is tightened to ±0.5% maximum, and the device is screened per MIL-STD-883B Level B to ensure this performance holds under thermal stress and burn-in conditions. This specification is confirmed in Table 1 of the AD632 Rev. D datasheet under the AD632T column.
Does AD632TD/883B support true four-quadrant multiplication with differential inputs on all three terminals (X, Y, and Z)?
Yes, AD632TD/883B supports fully differential operation on X, Y, and Z inputs: X₁/X₂ and Y₁/Y₂ form true differential multiplicands, while Z₁/Z₂ constitute a differential summing node. This enables floating-ratio division and rejection of common-mode interference in high-noise environments - a key differentiator from AD532, which lacks differential Z capability.
What package type and screening level does AD632TD/883B use, and how is it documented in the ordering guide?
AD632TD/883B uses the 14-lead side-brazed ceramic dual in-line package (SBDIP, D-14) and is screened to MIL-STD-883B Level B. This is explicitly stated in the Ordering Guide (Page 11 of Rev. D datasheet), where "AD632TD/883B" is listed with "−55°C to +125°C" temperature range and "14-Lead Side-Brazed Ceramic Dual In-Line Package [SBDIP]" package description.
Can AD632TD/883B be used as a precision squarer or square-rooter, and what are the respective error limits?
Yes, AD632TD/883B supports both functions: as a squarer with transfer function (X₁−X₂)²/10 + Z₂ and ±0.6% total error (−10 V ≤ X ≤ +10 V); as a square-rooter with transfer function √[10(Z₂−Z₁)] + X₁ and ±1.0% total error (1 V ≤ Z ≤ 10 V). These modes are detailed in the Squarer and Square-Rooter Performance sections of the Rev. D datasheet.
How does the VOS pin function in AD632TD/883B, and what is its adjustment range?
The VOS pin on AD632TD/883B accepts an external trim voltage of ±30 mV to null output offset voltage, which is specified as ±2 mV max at +25°C and ±5 mV max over temperature. This adjustment is optional - the device meets all specifications without trimming - but enables sub-millivolt DC accuracy in metrology-grade applications where offset drift must be actively canceled.
