can generate sine, triangle, and sawtooth waves for analog synthesizers. 4. Audio Compressors/Sustainers

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

Two OTAs in one 16-pin package, sharing common supplies but operating independently. 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?

. Often referred to as the "Swiss Army Knife" of analog design, this dual-operational transconductance amplifier (OTA) IC is a legendary component that brings voltage-controlled versatility to electronics. can generate sine, triangle, and sawtooth waves for

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

Built-in Darlington buffers allow for easy conversion of output current into voltage, complementing the amplifier's dynamic range. Gmcap G sub m Adjustable Over 6 Decades: Extremely flexible gain control. Common LM13700 Application Circuits Tips for Working with the It typically runs

Unlike a traditional Operational Amplifier (Op-Amp) that produces an output voltage proportional to the input, an OTA produces an output current proportional to the input voltage difference. The magic lies in the Amplifier Bias Current ( IABCcap I sub cap A cap B cap C end-sub
