THAT 2180 C
THAT 2180-series pre-trimmed Blackmer voltage controlled amplifiers (VCAs) ICs 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.
