LM13600N Dual Operational Transconductance Amplifier (OTA) DIP-16 (LM13600N DIP IC)
The LM13600N is a high-performance monolithic integrated circuit consisting of two independent operational transconductance amplifiers (OTA). Each amplifier features differential inputs and a push-pull output. A unique aspect of the LM13600N is the inclusion of internal linearizing diodes at the inputs, which significantly reduces distortion and allows for higher input signal levels. Additionally, each OTA is equipped with an independent Darlington emitter follower buffer to provide low-impedance output drive capability.
This IC is primarily used in voltage-controlled amplifiers (VCA), voltage-controlled filters (VCF), and voltage-controlled oscillators (VCO). It is a highly specialized and legendary component for Arduino electronics projects in India involving analog music synthesis, DIY modular synthesizers, automated gain control (AGC) circuits, and voltage-tunable active filters.
