Ultra-Low Noise Voltage Controlled Amplifier V2159
1. Description
The V2159 is a state-of-the-art voltage-controlled amplifier (VCA) offering high-performance current–in/current-out technology including two opposing-polarity, voltage-sensitive control ports. The V2159 VCA combines many advantages such as ultra-low noise, ultra-low distortion, low offset and high gain-bandwidth. It requires few external support circuitry and is housed in a space-efficient 8-pin single–in–line (SIP) package.

5. Function Description
The V2159 VCA is designed for high performance in audio applications which requires exponential gain control, low distortion, wide dynamic range and low DC “control feedthrough” modulation. Gain is controlled by converting an input current signal to a bipolar logged voltage, adding a DC control voltage and reconverting the summed voltage back to a current through a bipolar antilog circuit. The simplified internal circuit diagram of the IC is shown in figure 1. The AC input signal current flows in the input pin 1, which is maintained at a virtual ground by an internal opamp.
