P-Q-SSI2164 Integrated Circuit - SSI2164, Quad VCA, Sound Semiconductor
The FatKeys™ SSI2164 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. The SSI2164 is a versatile VCA building block for high-performance audio applications. Four independent channels provide voltage control of current-mode inputs and outputs for a gain range from +20dB to –100dB, with control provided by a ground-referenced –33mV/dB constant. The SSI2164 will directly retrofit existing SSM/V2164 positions while offering improvements that include significantly lower overall distortion, on-chip protection against asymmetrical power failure, and a substantial increase of input current handling. The device offers considerable flexibility for a wide range of design goals and applications.

P-Q-SSI2144 Integrated Circuit - SSI2144, Ladder VCF, Sound Semiconductor
The second of two legendary SSM filter updates, the FatKeys™ SSI2144 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. The SSI2144 reprises the SSM2044 of legacy chipmaker Solid State Micro Technology, which many believe to be the best-sounding analog synthesis filter IC ever produced. Based on Dave Rossum’s patented classic improved ladder topology, the SSI2144 allows rich tonal characteristics that showcase the very best attributes of subtractive synthesis. The SSI2144 uses the same internal circuit as the SSM2044 but incorporates improvements by the original designer and takes advantage of modern process technology.

P-Q-SSI2161 Integrated Circuit - SSI2161, Single VCA, Sound Semiconductor
A very high performance single-channel VCA for the most demanding applications, the ProCircuit™ SSI2161 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. The SSI2161 is a versatile VCA building block for high-performance audio applications. A single channel provides voltage control of current-mode inputs and outputs for a gain range from +20dB to –100dB, with control provided by a ground-referenced –33mV/dB constant. The device offers considerable flexibility for a wide range of design goals and applications. A unique mode control allows selection of Class A, Class AB, or in-between using a single resistor. In addition, improved current handling allows use of lower value input resistors for reduced output noise without loss of headroom.

P-Q-SSI2162 Integrated Circuit - SSI2162, Dual VCA, Sound Semiconductor
The FatKeys™ SSI2162 provides two independent VCA channels, and like its SSI2161 and SSI2164 siblings offers great flexibility in design of dynamics processors, automatic or remote level control, and voltage controlled filters. Highly compact 10-lead SSOP package. The SSI2162 is a versatile VCA building block for high-performance audio applications. Two independent channels provide voltage control of a current-mode input and output for a gain range from +20dB to –100dB, with control provided by a ground-referenced –33mV/dB constant. The device offers considerable flexibility for a wide range of design goals and applications. A unique mode control allows selection of Class A, Class AB, or in-between using a single resistor. In addition, improved current handling allows use of lower value input resistors for reduced output noise without loss of headroom. Both channels can be parallel-connected for further noise improvement.
