Blackmer Pre-Trimmed IC Voltage Controlled Amplifiers THAT 2180A, 2180B, 2180C FEATURES APPLICATIONS Wide Dynamic Range: >120 dB Faders Panners Wide Gain Range: >130 dB Compressors Exponential (dB) Gain Control Expanders Low Distortion: < 0.01 % (2180A) Equalizers Wide Gain-Bandwidth: 20 MHz Filters Dual Gain-Control Ports (pos/neg) Oscillators Pin-Compatible with 2150-Series Automation Systems Description THAT 2180 Series integrated-circuit voltage The VCA design takes advantage of a fully controlled amplifiers (VCAs) are very high- complementary dielectric isolation process performance current-in/current-out devices which offers closely matched NPN/PNP pairs, to with two opposing-polarity, voltage-sensitive deliver discrete performance at IC prices. The control ports. They offer wide-range exponen- parts are available in three grades, selected for tial control of gain and attenuation with low factory trimmed distortion, allowing the user to signal distortion. The parts are trimmed at optimize cost vs. performance. The 2180 Series wafer stage for low THD and control-voltage is available in an 8-pin single-in-line (SIP) feedthrough without further adjustment. package.
