Sound Semiconductor  FATKEYS ™ Analog Chips

SSI2144 SSOP to SSM2044 Adapter PCB

This adapter PCB converts the SSOP SSI2144 VCF to fit in a DIP-16 SSM2044 socket.

The PCB measures 21x11mm.

It allows you to retrofit vintage synthesizers based on the SSM2044 VCF with the new SSI2144 VCF chip.

SSI2144 VCF

The SSI2144 reprises the SSM2044 of legacy chipmaker

Solid State Microtechnology, 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 in a SSOP-16 package.
