Product Summary

The THAT2155 is an IC voltage-controlled amplifier. The THAT2155 integrated-circuit voltagecontrolled amplifier (VCA) is high-performance current-in/current-out devices with two opposingpolarity, voltage-sensitive control ports. Based on dbx technology, the THAT2155 offers wide-range exponential control of gain and attenuation with low signal distortion. The parts of the THAT2155 are housed in a space-efficient, plastic 8-pin single-in-line (SIP) package, and require minimal support circuitry. Fabricated in a super low-noise process utilizing high hFE, complementary NPN/PNP pairs, the THAT2155 VCA combine high gain-bandwidth product with low noise, low distortion, and low offset to offer discrete performance at IC prices. The THAT2155 is available in three grades, selected for distortion, allowing the user to optimize cost vs. performance.
