AD632SH

Overview

The AD632SH is a monolithic four-quadrant multiplier and divider manufactured by Analog Devices Inc. It operates within a temperature range of -55°C to +125°C and utilizes a hermetically sealed 10-pin metal header (TO-100) package. The device features a transfer function defined as VOUT = [(X1 − X2)(Y1 − Y2)/10] + Z2, with all inputs being differential and high impedance. It supports supply voltages from ±8 V to ±22 V and draws a quiescent current of 4 mA to 6 mA.

Feature Summary

• Internally trimmed for high precision with guaranteed maximum multiplying errors over the extended temperature range.
• Features fully differential, high-impedance inputs for X, Y, and Z channels to facilitate complex signal processing.
• Includes an adjustable scale factor that allows for gain settings up to ×10 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 the specific suffix 'SH' indicates the military-grade screening and TO-100 metal can package configuration. Confirm that the required operating temperature range aligns with the -55°C to +125°C specification. Ensure the application circuit accommodates the hermetic sealing requirements associated with this package style.

Selection Notes

Select the AD632SH when operation in extreme environments between -55°C and +125°C is mandatory. This variant provides MIL-STD-883 Level B screening options for enhanced reliability. Choose this model over standard commercial variants if long-term stability and high-reliability performance are critical design constraints.

Part Context

This component belongs to the AD632 series of internally trimmed precision IC multipliers. It serves as a pin-for-pin compatible upgrade to the industry-standard AD532, offering improved specifications such as a fully differential high-impedance Z input. The series includes various accuracy grades and packaging options tailored for different industrial and aerospace applications.

Replacement Considerations

The AD632AD is a commercial equivalent but lacks the extended temperature range and hermetic sealing. For direct replacement in military or aerospace contexts, verify compatibility with the AD632SH/883B variant which shares the same package and screening level.
