AD532SH

Overview

The AD532SH is a monolithic analog multiplier and divider housed in a TO-100-10 metal header package. It operates with dual supplies ranging from ±10 V to ±22 V, drawing a quiescent current of 6 mA. The device supports a transfer function of (X1 − X2)(Y1 − Y2)/10 V for multiplication, division, squaring, and square rooting. It guarantees a maximum multiplying error of ±4% over the extended temperature range of -55°C to +125°C. The small-signal bandwidth is 1 MHz, with a slew rate of 45 V/μs and a settling time of 1 μs.

Feature Summary

• Internally laser-trimmed monolithic construction eliminates the need for external trimming resistors or output operational amplifiers.
• Features differential X and Y inputs providing high common-mode rejection ratio for noise reduction and computational flexibility.
• Supports four-quadrant multiplication, two-quadrant division, squaring, and square rooting operations within a single chip.

Applications

• Multiplication, division, squaring, and square rooting
• Algebraic computation
• Power measurements
• Instrumentation applications

Procurement Notes

Verify the specific suffix 'SH' corresponds to the TO-100-10 metal header package and the -55°C to +125°C military-grade temperature rating. Confirm RoHS compliance status if required by the application, as standard versions may differ. Ensure supply voltage limits align with the ±10 V to ±22 V operating range specified for the S grade. Check for availability constraints as this component may have limited stock or discontinuation risks.

Selection Notes

Select the AD532SH when an extended industrial or military temperature range (-55°C to +125°C) is required alongside high accuracy. This model guarantees a maximum total error of ±4% across the full temperature range, compared to ±1% at 25°C for lower grades. Choose this package type for hermetically sealed environments requiring the TO-100 form factor. Consider the 1 MHz bandwidth and 45 V/μs slew rate for dynamic signal processing needs.

Part Context

The AD532 series represents Analog Devices' first pretrimmed, single-chip monolithic multiplier/divider. The AD532SH belongs to the 'S' grade family, designed for harsh environments with an extended temperature range. It serves as a direct replacement for older modular multipliers that require complex external trim networks, offering simplified design through integrated on-chip trimming and differential input capabilities.

Replacement Considerations

The AD532SH can replace other IC multipliers requiring external trim networks by grounding the X2, Y2, and VOS terminals. For pin-compatible alternatives in the same package, consider the AD532JHZ or AD532KHZ for commercial temperature ranges. Verify that the replacement part meets the specific ±10 V to ±22 V supply requirements and differential input configurations.

FAQ

What is the transfer function for the AD532SH in multiplication mode?

The transfer function for multiplication is (X1 − X2)(Y1 − Y2)/10 V.

How does the AD532SH handle power supply variations?

It operates from ±10 V to ±22 V. Power supply sensitivity is improved because it uses internal ratiometric trimming rather than external null networks.

Can the AD532SH perform division?

Yes, it performs two-quadrant division using the transfer function 10 V Z/(X1 − X2), where the denominator (X1 − X2) must be negative.
