Product description
The SSI2162 is a versatile VCA building block for high-performance audio applications.
Two independent channels provide voltage control of a current-mode input and output 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. Both channels can be parallel connected for further noise improvement. Finally, SSI2162 VCA channels can be used as high-quality OTA building blocks for a variety of applications such as voltage controlled filters, exponential generators, and antilog converters. The SSI2162 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 SSI2162 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 single-channel SSI2161 provides lowest noise.
