AD532KHZ

Overview

The AD532KHZ is a pretrimmed, single-chip monolithic analog multiplier and divider manufactured by Analog Devices. It guarantees a maximum multiplying error of ±1.0% at 25°C with no external trimming components required. The device features differential inputs supporting the transfer function (X1 − X2)(Y1 − Y2)/10 V. It operates on rated ±15 V supplies within an operating range of ±10 V to ±18 V. The component is housed in a hermetically sealed 10-pin metal header package (H-10) and is specified for operation from 0°C to 70°C.

Feature Summary

• Internally laser-trimmed monolithic construction eliminates the need for external trimming resistors or output operational amplifiers.
• Differential X and Y inputs provide high common-mode rejection and flexibility for algebraic computation and transducer instrumentation.
• Supports four-quadrant multiplication, two-quadrant division, squaring, and square rooting functions.

Applications

• Multiplication, division, squaring, and square rooting operations
• Algebraic computation and trigonometric calculations
• Power measurements and modulation applications
• Instrumentation applications involving transducer signal products

Procurement Notes

Verify that the ordering suffix 'HZ' corresponds to the 10-pin metal header package (H-10) as listed in the official Analog Devices ordering guide. Confirm RoHS compliance status indicated by the 'Z' suffix. Ensure application requirements align with the 0°C to 70°C temperature range specified for the K grade. Check datasheet specifications for supply voltage limits and input signal ranges before integration.

Selection Notes

Select the AD532KHZ when a guaranteed ±1.0% total multiplying error at 25°C is required without external calibration networks. Choose this variant over the J grade for tighter accuracy specifications. Consider the H-10 package if hermetic sealing is necessary for the environment. Verify that the ±10 V to ±18 V operating supply range meets system power constraints. Evaluate the 1 MHz small-signal bandwidth against dynamic signal requirements.

Part Context

The AD532 series represents the first pretrimmed, single-chip monolithic multiplier/divider from Analog Devices. It serves as a direct replacement for older IC multipliers requiring external trim networks. The K grade specifically denotes the ±1.0% error specification at room temperature. The HZ suffix identifies the specific package style and compliance status within the broader AD532 product family.

Replacement Considerations

The AD532 can replace other IC multipliers requiring external trim networks by grounding the X2, Y2, and VOS terminals. No direct pin-for-pin substitute part numbers are documented in the provided source material.
