Texas Instruments LM13700 Dual Transconductance Amplifier SOIC-16 2 MHz

The Texas Instruments LM13700 Dual Transconductance Amplifier is a dual operational transconductance amplifier with a 2 MHz gain bandwidth product, built for precision analogue signal processing.

Each amplifier features differential inputs and a push-pull output, operating independently while sharing common power supplies. Integrated linearising diodes at the inputs reduce harmonic distortion and permit higher input signal levels. This design delivers a 10 dB improvement in signal-to-noise ratio when referenced to 0.5% total harmonic distortion (THD), supporting cleaner audio and signal fidelity.

Overview

High-impedance output buffers are designed to match the dynamic range of the core amplifiers. In this device, the buffer input bias currents, and therefore their output DC levels, are independent of the amplifier bias current. This architecture can yield superior audio performance compared with earlier designs such as the LM13600.

The adjustable transconductance spans six decades with excellent linearity. The two amplifiers are very closely matched, which is critical for stereo and differential applications. The device is ideal for industrial control systems.
