High performance (100 d B dynamic range, 0.02% THD) is provided at a very low cost-per-VCA, resulting in excellent value for cost sensitive gain control applications. Each VCA offers current input and output for maximum design flexibility, and a ground referenced - 33 m V/d B control port. All channels are closely matched to within 0.07 d B at unity gain, and 0.24 d B at 40 d B of attenuation. A 120 d B gain range is possible. A single resistor tailors operation between full Class A and AB modes. The pinout allows upgrading of SSM2024 designs with minimal additional circuitry. The SSM2164 will operate over a wide supply voltage range of ± 4 V to ± 18 V. Available in 16-pin P-DIP and SOIC packages, the device is guaranteed for operation over the extended industrial temperature range of - 40°C to +85°C.
