GENERAL DESCRIPTION
The SSM2018T represents 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 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 trans-
parency. Additional features include differential inputs, a 140 dB
(–100 dB to +40 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 16-lead plastic DIP and SOIC packages
and guaranteed for operation over the extended industrial tempera-
ture range of –40
∞C to +85∞C.
