SOUND SEMICONDUCTOR INTRODUCES MIXER CHIP
Provides Voltage Control of Six Inputs into a Single Output
October 22, 2024 ñ Arroyo Grande, California, USA ñ Sound Semiconductor, a chipmaker focused on development of high performing analog integrated circuits, today announced the ProCircuitô 6-into-1 Voltage Controlled Mixer.
Based on a new-generation Operational Transconductance Amplifier (ìOTAî; patent pending), the SSI2190 allows current-mode linear control of each channel. Differential voltage inputs provide design flexibility, and a high-compliance current output makes summing from multiple sources ñ including other SSI2190ís ñ an easy endeavor.
In addition to the most obvious application ñ mixing of multiple audio inputs into a single output ñ the 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 oneís 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 SSI2190ís 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 OEMís.
"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!"
