AD632TH

Overview

The AD632TH is a monolithic four-quadrant multiplier and divider manufactured by Analog Devices. It features an internally trimmed design with a maximum multiplying error of ±1.0% over the extended temperature range of −55°C to +125°C. The device utilizes a 10-pin Metal Header Package (H-10) and operates on supply voltages ranging from ±8 V to ±22 V. Key electrical specifications include a small signal bandwidth of 1 MHz, a slew rate of 20 V/µs, and a wideband noise of 90 µV rms between 10 Hz and 10 kHz.

Feature Summary

• Internally trimmed for high precision with guaranteed low multiplying errors across extreme temperatures.
• Features fully differential, high-impedance inputs for X, Y, and Z channels to support complex analog computations.
• Includes a stable reference and bias system utilizing on-chip thin film resistors and buried zener references.
• Capable of providing gains up to ×10 through adjustable scale factors without requiring external instrumentation amplifiers.

Applications

• High quality analog signal processing
• Differential ratio and percentage computations
• Algebraic and trigonometric function synthesis
• Accurate voltage controlled oscillators and filters

Procurement Notes

Verify that the specific order includes MIL-STD-883 Level B screening if required for your application, as indicated by the suffix designation in the ordering guide. Confirm package compatibility with the 10-pin Metal Header format. Ensure supply voltage limits are respected within the ±8 V to ±22 V operating range. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select the AD632TH when operation is required in environments ranging from −55°C to +125°C. This model provides a ±1.0% total error specification at full scale. Choose this variant over lower-grade models if extended temperature stability and high reliability are critical. The H-10 package is suitable for hermetically sealed applications or military-grade systems requiring robust physical construction.

Part Context

This component belongs to the AD632 family of precision IC multipliers. It serves as a pin-for-pin compatible alternative to the industry-standard AD532 but offers improved specifications. The AD632 series includes variants like the AD632AD and AD632BD for commercial temperature ranges, while the TH suffix specifically denotes the extended industrial/military temperature grade housed in a metal header package.

Replacement Considerations

The AD632TD is a direct functional replacement offering identical performance in a 14-lead ceramic DIP package. For hermetically sealed requirements, the AD632SH provides equivalent specifications in a 10-pin metal header package. If MIL-STD-883 screening is mandatory, consider the AD632TH/883B or AD632TD/883B variants.
