SSM2018:  Trimless Voltage Controlled Amplifier

Product Details


The SSM2018T represents the continuing evolution of the Frey Operational Voltage Controlled Element (OVCE) topology that permits flexibility in the design of high performance volume control systems. The SSM2018T offers voltage output and is laser-trimmed for gain core symmetry and offset. As a result, the SSM2018T is the first professional audio quality VCA to offer trimless operation.

Due to careful gain core layout, the SSM2018T combines the low noise of Class AB topologies with the low distortion of Class A circuits to offer an unprecedented level of sonic transparency. Additional features include differential inputs, a 140 dB gain range, and a high impedance control port. The SSM2018T provides an internal current-to-voltage converter; thus no external active components are required.

This device is offered in a 16-pin plastic DIP package and guaranteed for operation over the extended industrial temperature range of -40°C to +85°C.
