A refresh of a classic design, the FatKeys™ SSI2140 preverses mojo of the beloved SSM2040 and adds temperature compensation of gm cells and the exponential control port. A "Q VCA" is provided to allow easy resonance control as well as various options for Q compensation. The four transconductance cells are highly configurable for a variety of pole and mode combinations.

The SSI2140 is a new-generation voltage controlled filter that provides four highly-configurable variable transconductance cells for a wide variety of pole and mode combinations, and adds significant new features.

Based on an updated core by original SSM2040 designer Dave Rossum, the SSI2140 temperature compensates its transconductance cells for unprecedented stability. Temperature compensation is also optionally available for the exponential control.

A temperature compensated VCA with linear control allows easy control of resonance and supports multiple Q compensation schemes, or otherwise can be used for traditional VCA/VCF roles.

Virtually any type of filter response from one to four poles can be achieved including low-pass, high-pass, band-pass, all-pass, notch, Sallen & Key, biquad, Cauer, state-variable, and others.

Most importantly, great care was taken to preserve the SSM2040’s sonics including an input stage that can be overdriven for classic analog synthesizer character.

Features:

  • Highly Configurable Four-Section Filter
  • Preserves SSM2040’s Classic Filter Sound
  • Exponential Frequency Control, with Optional Temperature Compensation
  • On-Chip Resonance Circuit with Linear Control
  • Optional Q Compensation
  • ±4V to ±16V Operation
  • Ultra-Compact 20-Lead SSOP Package
