LM13600MX

Overview

The LM13600MX is a dual operational transconductance amplifier (OTA) manufactured by National Semiconductor, now part of Texas Instruments. It integrates linearizing diodes and output buffers within a single package. The device functions as a voltage-controlled current source, providing high-speed signal processing capabilities suitable for analog computation and modulation applications.

Feature Summary

• Dual operational transconductance amplifier architecture with integrated linearizing diodes
• Built-in output buffers to isolate the current source from load variations
• Voltage-controlled gain mechanism allowing precise modulation of transconductance

Applications

• Analog multipliers and mixers
• Voltage-controlled amplifiers (VCAs)
• Automatic gain control circuits
• Waveform shaping and distortion generation

Procurement Notes

Verify the manufacturer designation carefully, as National Semiconductor assets were acquired by Texas Instruments. Ensure the specific suffix matches the required tape-and-reel packaging configuration. Confirm that the component meets the necessary environmental compliance standards for the intended deployment region before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring voltage-variable gain or analog multiplication. The integrated linearizing diodes simplify biasing networks compared to discrete OTA solutions. Consider the output buffer characteristics if driving low-impedance loads directly without additional buffering stages.

Part Context

This component belongs to the family of dual operational transconductance amplifiers originally developed by National Semiconductor. These devices are fundamental building blocks in analog signal processing, offering a distinct alternative to standard voltage-output operational amplifiers by providing current outputs proportional to input voltage differences.

Replacement Considerations

The LM13700 is a widely recognized functional equivalent within the same product family. Verify pin compatibility and electrical parameter alignment, particularly regarding maximum supply voltages and output current limits, before substituting.
