A classic application is the compressor pedal (like the MXR Dyna Comp), where the output signal is used to drive the IABCcap I sub cap A cap B cap C end-sub pin, reducing gain when the input is too loud. Tips for Working with the It typically runs on
is an improved version of the older LM13600, offering several advantages for audio applications:
) pin. By injecting a small current into this pin, you control the transconductance ( Gmcap G sub m lm13720
But what makes this decades-old chip still relevant in 2026? Let's dive into the world of OTAs and why the remains indispensable. What is an OTA?
can generate sine, triangle, and sawtooth waves for analog synthesizers. 4. Audio Compressors/Sustainers A classic application is the compressor pedal (like
These integrated diodes reduce distortion, allowing higher input signal levels—crucial for audio quality.
can be used to build resonant low-pass, high-pass, or band-pass filters where the cutoff frequency is swept by a CV. 3. Voltage-Controlled Oscillator (VCO) By controlling the charging current of a capacitor, the Let's dive into the world of OTAs and
remains a pillar of analog DIY and synthesizer design. Its ability to create voltage-controlled systems simply and effectively, combined with the convenience of built-in buffers and linearizing diodes, ensures its place in the analog designer's toolkit for years to come.
