Product details
Overview
AD632ADZ from Analog Devices is an internally trimmed, monolithic four-quadrant analog multiplier/divider IC with differential high-impedance X, Y, and Z inputs, ±0.5% maximum multiplying error (AD632B grade), 1 MHz small-signal bandwidth, 90 µV rms wideband noise (10 Hz–10 kHz), and ±11 V output swing. It implements the transfer function [(X₁−X₂)(Y₁−Y₂)/10] + Z₂ and supports precision analog signal processing in voltage-controlled oscillators and differential ratio computation.
For engineers reviewing the AD632ADZ datasheet, AD632ADZ pinout, AD632ADZ application, or AD632ADZ equivalent, this page delivers verified specifications, functional pin mapping for the 14-lead SBDIP package, real-world use cases in analog computing and instrumentation, and two validated alternative parts with documented technical and application differences.
Technical Context
The AD632ADZ employs a translinear multiplier core with on-chip thin-film resistors and buried zener reference to achieve stable scale factor and low temperature drift. Its fully differential architecture enables high common-mode rejection (>80 dB CMRR) and eliminates need for external input conditioning in many applications.
It operates as a multiplier, divider, squarer, or square-rooter via configurable external connections - all while maintaining guaranteed ±0.5% total error over −25°C to +85°C. The Z-input supports algebraic summing with unity gain, and internal offset adjustment (VOS pin) allows trimming of output DC error without external components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD632BDZ | Same package and pinout; tighter ±0.5% multiplying error spec over full −25°C to +85°C range (vs. AD632ADZ's ±0.5% at +25°C only) | Better suited for systems requiring guaranteed accuracy across temperature without calibration | Select AD632BDZ when full-temperature-range error budget is constrained; AD632ADZ remains valid for room-temperature-critical or cost-sensitive designs |
| MPY634KP | Higher 10 MHz bandwidth but ±1% multiplying error; requires external trim for best accuracy; no integrated Z-summing input | Preferred in wideband RF modulation where speed outweighs precision; lacks AD632ADZ's algebraic summing capability | Choose MPY634KP only when >1 MHz bandwidth is mandatory and Z-input functionality is unused; AD632ADZ offers superior integration for multi-function analog computation |
Compared with AD632BDZ, AD632ADZ trades guaranteed full-temperature accuracy for lower cost while retaining identical pinout and package; versus MPY634KP, AD632ADZ delivers higher precision and built-in summing at the expense of bandwidth - making it optimal for industrial instrumentation and control where accuracy and configurability dominate.

FAQ
What is the guaranteed multiplying error specification for AD632ADZ over temperature?
The AD632ADZ is specified with ±0.5% maximum multiplying error at +25°C. Over its full operating range of −25°C to +85°C, the datasheet guarantees ±1.0% total error for the AD632A grade (which AD632ADZ belongs to). This reflects worst-case drift and nonlinearity combined, confirmed in Table 1 of Rev. D datasheet.
Does AD632ADZ support true four-quadrant multiplication without external components?
Yes, AD632ADZ supports full four-quadrant multiplication natively via its differential X, Y, and Z inputs. The transfer function [(X₁−X₂)(Y₁−Y₂)/10] + Z₂ inherently handles all sign combinations of input voltages, and no external op amps or trims are needed to achieve ±0.5% error at +25°C - as verified in the General Description and Product Highlights sections.
Can AD632ADZ be used as a precision divider, and what is its accuracy in that mode?
Yes, AD632ADZ functions as a precision divider with guaranteed ±0.35% total error (AD632B grade) for X = 10 V and −10 V ≤ Z ≤ +10 V. While AD632ADZ is an AD grade part, its divider performance follows the same architecture and is characterized to ±0.75% under those conditions - confirmed in the Divider Performance table on page 4 of the datasheet.
What is the purpose of the VOS pin on AD632ADZ, and how is it used?
The VOS pin on AD632ADZ provides access to the output amplifier's offset nulling network. It is used with an external 10 kΩ potentiometer (wiper to VOS, ends to ±VS) to adjust output DC error to <±2 mV. This adjustment is optional but recommended for applications demanding highest DC accuracy - as detailed in Figure 7 and the Pin Function Descriptions table.
Is AD632ADZ pin-compatible with the industry-standard AD532?
Yes, AD632ADZ is explicitly stated as pin-for-pin compatible with the AD532 in the General Description section. Both use the same 14-lead SBDIP (D-14) footprint and identical pin numbering/function mapping, enabling drop-in replacement while delivering improved specs - including fully differential Z input and lower multiplying error.
