MPY534LD

Overview

The MPY534LD is a precision analog multiplier and divider manufactured by Burr Brown, now part of Texas Instruments. It features a 14-CDIP package and bipolar technology with a 3MHz bandwidth. The device provides internally trimmed accuracy with an error specification of ±0.25% and a temperature coefficient of 0.008%/°C.

Feature Summary

• Performs linear analog multiplication and division functions
• Supports four-quadrant operation for signal processing
• Includes internal trimming for high precision

Applications

• Signal processing circuits
• Frequency synthesis systems
• Automatic gain control loops

Procurement Notes

Verify the manufacturer designation as Burr Brown or Texas Instruments on the component marking. Confirm the 14-CDIP package type matches the required footprint. Ensure the specific suffix LD corresponds to the desired accuracy class of ±0.25%. Check for authenticity through authorized distributors or certified suppliers.

Selection Notes

Select this component when high-precision analog multiplication or division is required in bipolar applications. The 3MHz bandwidth suits moderate-speed signal processing tasks. Compare against similar models like MPY534KD or AD534TD based on specific accuracy and package requirements. Verify that the CDIP package fits the target PCB design constraints.

Part Context

This component belongs to the MPY534 family of analog multipliers and dividers. Other variants include MPY534SD and MPY534SH, which offer different accuracy levels and temperature coefficients. The family is designed for precision instrumentation and signal processing applications requiring reliable analog computation capabilities.

Replacement Considerations

The AD534TD/883B is documented as a comparable internally trimmed precision IC multiplier. Verify pin compatibility and electrical specifications before substitution. Ensure the replacement meets the required bandwidth and accuracy standards for the specific application.
