AD632SH/883B

Overview

The AD632SH/883B is a monolithic four-quadrant multiplier and divider manufactured by Analog Devices. It operates within an extended temperature range of -55°C to +125°C and features a maximum multiplying error of ±2.0%. The device utilizes a 10-pin TO-100 metal header package (H-Package) and requires a supply voltage operating between ±8 V and ±22 V, with rated performance at ±15 V. It draws a quiescent supply current of 4 mA to 6 mA. Key dynamic specifications include a small-signal bandwidth of 1 MHz, a slew rate of 20 V/µs, and a settling time of 2 µs. The wideband noise is specified at 90 µV rms from 10 Hz to 10 kHz.

Feature Summary

• Internally trimmed for high precision with guaranteed low multiplying errors across the full military temperature range.
• Features fully differential, high-impedance inputs for X, Y, and Z channels to support complex signal processing functions.
• Includes a stable on-chip reference and bias circuitry utilizing thin film resistors and buried zener references for long-term stability.
• Capable of providing scale factors up to ×10 gain, reducing the need for 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 ordering suffix /883B confirms compliance with MIL-STD-883 Level B screening requirements as indicated in the manufacturer's documentation. Confirm the package type matches the 10-pin TO-100 metal header specification. Ensure the procurement channel provides traceability for military-grade components. Check for RoHS status if required by the final assembly process, noting that standard versions may differ from screened variants.

Selection Notes

Select this component when operation in extreme environments ranging from -55°C to +125°C is mandatory. Choose the SH/883B variant specifically for applications requiring MIL-STD-883 Level B screening and hermetically sealed packaging. Consider this part over lower-grade variants if the design demands a guaranteed maximum multiplying error of ±2.0% across the entire temperature spectrum rather than just at room temperature.

Part Context

This component belongs to the AD632 series of internally trimmed precision IC multipliers produced by Analog Devices. It serves as a high-reliability alternative to commercial grade parts, offering improved specifications and robust construction suitable for demanding aerospace and defense sectors. The device maintains pin-for-pin compatibility with industry standards while providing enhanced accuracy and stability through its monolithic construction.

Replacement Considerations

The AD632SH is the non-screened equivalent of this part number. Other variants in the family include AD632TD and AD632TH for different package options within the same temperature range.
