SSI2190

Based on the new Sound Semiconductor OTA circuit, the ProCircuit SSI2190 mixes six inputs into a single high compliance output. Each channel has differential voltage inputs with current-mode linear control. In addition to the obvious signal mixing, the SSI2190 can be creatively employed for phase correction, voltage controlled equalizers, pole mixing, and whatever else you can dream up.

The SSI2190 is a six-into-one voltage controlled mixer in a compact 24-lead SSOP package, based on a new-generation Operational Transconductance Amplifier (OTA) developed by Sound Semiconductor. The high-compliance current output allows easy paralleling of multiple SSI2190s.

Each input channel has differential voltage inputs and a cur- rent-mode linear control input. This combination results in low distortion and control feedthrough, along with wide dynamic range.
The SSI2190 makes mixing of audio signals - as well as control voltages - a simple endeavor. Differential inputs can be used for phase correction, differential signal paths, as well as countless other applications that are only limited to one's imagination. A minimum of inexpensive external components are required for operation.

A wide supply voltage range (single or dual) allows use in a variety of audio gear from musical instruments and effects pedals to prosumer systems where large signal handling and headroom are desired.
