A very high performance single-channel VCA for the most demanding applications, the
ProCircuit™ SSI2161 offers industry-leading lowest-noise, and a mode control to optimize noise vs. distortion performance. All at low-cost and in a 10-lead SSOP package.

The SSI2161 is a versatile VCA building block for high-performance audio applications. A single channel provides voltage control of current-mode inputs and outputs for a gain range from +20dB to –100dB, with control provided by a ground-referenced –33mV/dB constant.

The device offers considerable flexibility for a wide range of design goals and applications. A unique mode control allows selection of Class A, Class AB, or in-between using a single resistor. In addition, improved current handling allows use of lower value input resistors for reduced output noise without loss of headroom. Finally, the VCA can be used as a high-quality OTA building block for a variety of applications such as voltage controlled filters, exponential generators, and antilog converters.

The SSI2161 will operate on supplies as low as +8V for battery-powered devices such as guitar pedals, or up to ±18V in systems where maximum headroom is desired.

The SSI2161 is part of a family of affordable high-performance VCA’s from Sound Semiconductor. The SSI2164 offers four VCA’s in a compact SOP package with lowest cost-per VCA, and the SI2162 provides two channels in a small PCB footprint. For the dual version, see P-Q-SSI2162. For the quad version, see P-Q-SSI2164.
