That 2180 VCA IC Available In 8 Pin SIP

THAT Corporation's 2180LB pre-trimmed VCA ICs are now available in small quantities at affordable prices. You no longer have to an entire tube when you need just a few. This is the selected, yet affordable B-grade 2180 available from THAT Corporation and is suitable for the GSSL Clone and other applications.

THAT 2180 Series integrated circuit Blackmer voltage controlled amplifiers (VCAs) are high-performance current-in/current-out devices with two opposing-polarity, voltage-sensitive control ports. They offer wide-range exponential control of gain and attenuation with low signal distortion. The parts are trimmed during wafer processing to minimize THD and control-voltage feedthrough. After packaging, the parts are tested and graded based on the degree to which the trim survived packaging. No further adjustment is required to achieve the guaranteed distortion and feedthrough performance.

THAT Blackmer VCAs are the successors to the original dbx line of VCAs. To overcome the problems related to limited GBW product, the 218X series of VCAs, was developed by Gary Hebert in a dielectrically isolated process, and has topological enhancements that minimize the effect of non-linearities in the VCA drive circuitry on high frequency distortion. These VCAs are equal or superior to their predecessors in every regard, and in particular, do not exhibit the rising distortion at higher frequencies characteristic of VCAs built on a junction isolated process.
