Linear Integrated Systems VCR11N TO-71 6L

A voltage-controlled resistor (VCR) is a three-terminal variable resistor in which the resistance between two terminals is controlled by the voltage potential applied to the third terminal. The VCR is capable of operating as a symmetrical resistor with no DC bias voltage in the signal loop, making it ideal for many applications.

The VCR11N is particularly suited for applications involving low-level AC signals with no DC component across the drain-source terminals. The key performance characteristic of this device is the predictable variation of drain-source resistance (RDS) for a given gate-source voltage. The VCR11N is housed in a TO-71 6-pin package.
