Sound Semiconductor, a chipmaker focused on development of high performing analog integrated circuits for use in synthesizers and other applications, has introduced the SSI2190 ProCircuit 6-into-1 Voltage Controlled Mixer.

Sound Semiconductor is the ‘spiritual successor’ to pioneering synth chip maker Solid State Music (SSM), which, along with Curtis Electromusic Specialties, manufactured integrated circuits that helped make the first generation of affordable analog polysynths and other electronic instruments possible.

The SSI2190 Voltage Controlled Mixer, like the company’s other analog chip solutions, is designed to be a flexible building block for making synthesizers and other audio gear. It’s based on an original Operational Transconductance Amplifier (OTA) design and offers current-mode linear control of each channel.

Differential voltage inputs provide design flexibility, and a high-compliance current output makes summing from multiple sources, including other SSI2190’s, easy.

In addition to basic use cases – like mixing of multiple audio inputs into a single output – the SSI2190 can be used for more complex use cases, such as voltage controlled equalizers, pole mixing, phase correction, and mixing of control voltages.

Offered in a 28-lead SSOP package, only a handful of external components are necessary.

“I’m really excited about the potential of this new chip”, said co-designer Neil Johnson, adding, “it’s the first new mixer IC in decades, and I can’t stop thinking up new applications for it!”

Pricing and Availability:

The SSI2190 Voltage Controlled Mixer is available now, priced at $1.93 at 1000 pieces, with stock available for immediate delivery or sampling to qualified OEM’s.
