The SSM-2013 is a high-performance monolithicClass A Voltage Controlled Amplifier.

Operatingwith current modeinputsand outputs. the SSM-2013 is ideal when logarithmic control of gain is needed. The output current gain or attenuation is controlled by applying a control \/oltage to the EXPO pin 9. The amplifier offers wide bandwidth. easy signal summing and minimum external component count. The SSM-2013 can operate with more than 12dB of headroom at the rated specifications or be configured for gains as high as 40dB. Inherently low control feedthrough and 2nd harmonic distortion make trimming unnecessary for most applications. An extremely wide control range of 11Ode regulated by a flexible antilogarithmic control port make this VCA a versatile analog building block. With 800kHz bandwidth and 94dB SIN ratio at 0.01% THO. the SSM-2013 provides a useful solution for a variety of signal conditioning needs in applications ranging from professional audio to analog instrumentation, process controls and more.

Precision Monolithics, Inc. also known as PMI, was an American company based in Santa Clara, California, that developed and produced mixed signal and linear integrated circuits (ICs)

PMI also bought Solid State Micro Technology. Erdi and Khadder left PMI in 1981 to co-found Linear Technology. PMI was founded with financing from Bourns, Inc., which held 70% of the shares and 30% was stock purchased at a nominal price by the founders. Ultimately, all shares were purchased by Bourns to make PMI a wholly owned subsidiary, PMI was finally bought by Analog Devices in August 1990.
