SSM2018TP

免调节压控放大器 Trimless Voltage Controlled Amplifiers

GENERAL DESCRIPTION

The SSM2018T and SSM2118T represent continuing evolution of the Frey Operational Voltage Controlled Element OVCE topology that permits flexibility in the design of high performance volume control systems. Voltage SSM2018T and differential current SSM2118T output versions are of fered, both laser-trimmed for gain core symmetry and offset. As a result, the SSM2018T is the first professional audio quality VCA to offer trimless operation. The SSM2118T is ideal for low noise summing in large VCA based systems.
