AD532KD/+

Overview

The AD532KD/+ is a pretrimmed, monolithic analog multiplier and divider manufactured by Analog Devices. It operates with a rated supply voltage of ±15 V and supports an operating range from ±10 V to ±18 V. The device guarantees a maximum multiplying error of ±1.0% at 25°C and features a small signal bandwidth of 1 MHz. It utilizes differential inputs for X and Y channels with a transfer function of (X1 − X2)(Y1 − Y2)/10 V. The component is housed in a 14-lead side-brazed ceramic dual in-line package.

Feature Summary

• Internally laser trimmed to eliminate the need for external trimming resistors or output operational amplifiers.
• Features high impedance differential inputs for both X and Y channels to enhance noise rejection and computational flexibility.
• Monolithic construction provides improved reliability and reduced power requirements compared to hybrid modular multipliers.

Applications

• Multiplication, division, squaring, and square rooting operations
• Algebraic computation and modulation applications
• Power measurements and instrumentation systems

Procurement Notes

Verify that the specific part number matches the required temperature grade and package option. Confirm RoHS compliance status via the ordering guide suffix. Ensure the design accommodates the specified supply voltage range and thermal resistance characteristics for the selected package type.

Selection Notes

Select this component when a single-chip solution with guaranteed accuracy is required without external trim networks. Consider the ±1.0% total error specification for precision applications. Evaluate the 1 MHz bandwidth against system frequency requirements. Verify compatibility with the available 14-lead ceramic DIP package constraints.

Part Context

This device belongs to the AD532 family of internally trimmed integrated circuit multipliers. It serves as a direct replacement for older IC multipliers requiring external trim networks. The family includes variants with different temperature ranges and error specifications, such as the AD532J and AD532S grades.

Replacement Considerations

The AD532 can replace other IC multipliers requiring external trimming by grounding the X2, Y2, and VOS terminals. Verify pin-for-pin compatibility with existing designs. Ensure the new configuration meets the required polarity and offset nulling needs.
