HIGH PERFORMANCE IC’S FOR MUSIC CREATION
We were really excited to bring this range to Thonk in 2021. Sound Semiconductor have a stunning range of IC’s including the Dave Rossum designed SSI2140 filter as used in the brand new Sequential Prophet 5 rev4. Sound Semiconductor are powering a whole new age of analogue synths.
Sound Semiconductor are a veteran team of musicians and technologists with a passion for audio. Their charter is to develop best-in-class integrated circuits for electronic musical instruments, effects, signal processors, mixers, and anything else that helps musicians create music.
SSI2190 – Voltage Controlled Mixer — NEW!
Based on a new OTA circuit, the ProCircuit™ SSI2190 mixes six inputs into a single high compliance output! Each channel has differential voltage inputs with current-mode linear control. In addition to the obvious signal mixing, the SSI2190 can be creatively employed for phase correction, voltage controlled equalizers, pole mixing, and whatever else you can dream up!

SSI2131 – Voltage Controlled Oscillator
The SSI 2131 is a new-generation voltage controlled oscillator with buffered triangle, sawtooth, and variable-width pulse waveform outputs over a ten-octave range. The device offers unprecedented levels of temperature stability, exponentiality, waveform integrity, and ease of use while requiring an absolute minimum of external components.

SSI2140 / SSI2140DAB – Voltage Controlled Multi-Mode Filter
A refresh of a classic design, the FatKeys™ SSI 2140 preserves the 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 DAB variant, the SSI 2140DAB comes in a DIP-32 package spec for easier through-hole experimentation and testing.

SSI2144 – Voltage Controlled Low-Pass Filter
The second of two legendary SSM filter updates, the FatKeys™ SSI 2144 is a dedicated four-pole low-pass ladder filter with on-chip resonance control. Original designer Dave Rossum did a number of performance updates such as lower noise, improved control feedthrough, and logical pin grouping but otherwise left this sweet-sounding VCF alone.

SSI2164 – Voltage Controlled Amplifier
The FatKeys™ SSI 2164 is perhaps the most flexible VCA available, with four independent channels for lowest cost-per-VCA. The user-selectable mode control allows Class A, AB, or intermediate biasing, and current inputs and outputs provide great design freedom. Ideal for voltage-controlled filters.
This is a drop-in replacement for the Coolaudio V2164M

SSI2162 – Voltage Controlled Amplifier
The FatKeys™ SSI 2162 provides two independent VCA channels, and like its SSI 2161 and SSI 2164 siblings offers great flexibility in design of dynamics processors, automatic or remote level control, and voltage controlled filters. Highly compact 10-lead SSOP package.
Data Sheet | Package Spec. SSOP-10
SSI2161 – Voltage Controlled Amplifier
A very high performance single-channel VCA for the most demanding applications, the ProCircuit™ SSI 2161 offers industry-leading lowest-noise, and a mode control to optimize noise vs. distortion performance. All at low-cost and in a 10-lead SSOP package.

SSI2130 / SSI2130DAB – Voltage Controlled Oscillator
Designer Derek Bowers has been imagining this chip since building his first synth during college! The FatKeys™ SSI 2130 provides beautiful triangle, sawtooth, pulse, and square waveforms with unprecedented temperature stability; and adds an on-chip mixer, low distortion sine wave generator, through-zero FM/PM capability and more in an ultra-compact PCB footprint. The DAB variant, the SSI 2130DAB comes in a DIP-32 package spec for easier through-hole experimentation and testing. The SSIEVB2130 is a VCO Evaluation PCB. It comes with the tiny SSI2130 QFN SMD part pre-soldered, the rest of the BOM is all easy to solder through hole parts.
