LM13700MX

Overview

The LM13700MX is a dual operational transconductance amplifier manufactured by Texas Instruments. It integrates two high-performance transconductance amplifiers with linearizing diodes and output buffers within a single package. The device operates on a supply voltage range of 10 V to 36 V, supporting a maximum supply voltage of 36 V. Key electrical characteristics include a gain-bandwidth product of 2 MHz, a slew rate of 50 V/us, and an input bias current of 5 uA. The unit features a minimum forward transconductance of 5400 uS and a common-mode rejection ratio of 80 dB. It is housed in a surface-mount SOIC-16 package.

Feature Summary

• Integrates dual operational transconductance amplifiers with built-in linearizing diodes for improved linearity control.
• Includes high-current output buffers capable of driving external loads directly.
• Supports wide differential input voltages without requiring external protection components.

Applications

• Voltage-controlled amplifiers and attenuators
• Automatic gain control circuits
• Analog multipliers and mixers

Procurement Notes

Verify the specific suffix MX indicates the tape-and-reel packaging format distinct from tube versions. Confirm RoHS compliance status as NOPB variants may differ. Ensure the source document explicitly lists the LM13700MX part number rather than generic family data. Check for any specific handling instructions related to the SOIC-16 surface mount package.

Selection Notes

Select this component when designing circuits requiring precise voltage-controlled gain or analog multiplication functions. The integrated linearizing diodes simplify design compared to discrete solutions. Consider the 36 V maximum supply rating for higher voltage applications. Verify that the SOIC-16 footprint matches the target PCB layout constraints.

Part Context

This device belongs to the LM13700 series of dual operational transconductance amplifiers. It shares functional similarities with the LM13600 but offers enhanced performance specifications. The MX suffix specifically denotes the reel-packaged version intended for automated surface-mount assembly processes.
