Description

The THAT 2150 Series integrated-circuit voltage-

controlled amplifiers (VCAs) are high-performance

current-in/current-out devices with two opposing-

polarity, voltage-sensitive control ports. Based on

dbx technology, they offer wide-range exponential

control of gain and attenuation with low signal dis-

tortion. The parts are housed in a space-efficient,

plastic 8-pin single-in-line (SIP) package, and re-

quire minimal support circuitry. Fabricated in a

mentary NPN/PNP pairs, the 2150 Series VCAs

combine high gain-bandwidth product with low

noise, low distortion, and low offset to offer discrete

performance at IC prices. They are available in

three grades, selected for distortion, allowing the

user to optimize cost vs. performance.
