Sound Semiconductor SSI2190 6 into 1 Voltage Controlled Mixer (SSOP-24)

 Loading product data...

The Sound Semiconductor ProCircuit™ SSI2190 is a six-into-one voltage controlled mixer in a compact 24-lead SSOP package. This 6-way mixer is 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 current-mode linear control input. This combination results in low distortion and low control feedthrough, along with wide dynamic range.

The SSI2190 makes it simple to mix audio as well as control signals. Differential inputs can be used for phase correction, differential signal paths, as well as countless other applications. The SSI2190 requires only a minimum of inexpensive external components.

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.
