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 lm13720
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.
