Sound Semiconductor SSI2161 Voltage Controlled Amplifier (VCA) (SSOP-10)
This 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 and S/N ratio is desired.
This is one of a family of economical high performance VCAs from Sound Semiconductor. See the Related Products table below for additional SSI VCA products.
