2164 Quad VCA IC

3.69

The SSI2164 is a new and improved version of the renowned SSM2164 quad VCA IC. It has been used in countless analog VCAs, filters, and oscillators over the years.

Four independent channels provide 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 SSI2164 will directly retrofit existing SSM/V2164 positions while offering improvements that include significantly lower overall distortion, on-chip protection against asymmetrical power failure, and a substantial increase of input current handling. 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 considerably lower value input resistors for reduced output noise without loss of headroom. Two or more channels can be parallel-connected for further noise improvement. Finally, SSI2164 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 SSI2164 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.
