Description
THAT 2180 Series integrated-circuit voltage con-
trolled amplifiers (VCAs) are very high-performance
current-in/current-out devices with two oppos-
ing-polarity, voltage-sensitive control ports. They offer
wide-range exponential control of gain and attenuation
with low signal distortion. The parts are trimmed at
wafer stage for low THD and control-voltage
feedthrough without further adjustment.
The VCA design takes advantage of a fully comple-
mentary dielectric isolation process which offers
closely matched NPN/PNP pairs, to deliver discrete
performance at IC prices. The parts are available in
three grades, selected for factory trimmed distortion,
alowing the user to optimize cost vs. performance. The
2180 Series is available in an 8-pin single-in-line (SIP)
package.
