Sound Semiconductor is a chipmaker from California, focused on development of high performing analog integrated circuits. The company was founded by musicians and technologists with the goal of developing affordable, high-performance integrated circuits for music creation.
In addition to the most obvious application - mixing of multiple audio inputs into a single output - the new SSI2190 can be used for countless applications such as voltage controlled equalizers, pole mixing, phase correction, or mixing of control voltages. As a generic audio building block, applications are only limited by one’s imagination.
The SSI2190 operates from a wide supply voltage range of ±4V to ±18V or 8V to 36V in single-supply systems. As a result, 10VRMS input signals can be easily handled when high-headroom is needed (±15V supplies). Low THD (0.025% at VIN = 0dBu), 113dB Dynamic Range (±15V supplies), and 100dB mute attenuation round out the SSI2190’s performance.
Offered in a 28-lead SSOP package, only a handful of external components are necessary. Pricing is $1.93 at 1000 pieces, with stock available for immediate delivery or sampling to qualified OEM’s.
“I’m really excited about the potential of this new chip,” says 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!”
