The THAT 2180B is a pre-trimmed Blackmer voltage-controlled amplifier (VCA) IC from THAT Corporation. It is a current-in/current-out device with two opposing-polarity, voltage-sensitive control ports, enabling wide-range exponential control of gain and attenuation with low signal distortion.
Key electrical specifications include a dynamic range exceeding 120 dB and a gain range greater than 130 dB. It offers a wide gain-bandwidth of 20 MHz. The device is designed for low distortion, with the 2180A grade specified at less than 0.01% THD. The 2180B grade typically exhibits 0.01% THD at 1V, 0dB gain.
Applications for the 2180B include faders, panners, compressors, expanders, equalizers, filters, oscillators, and automation systems. The VCA design utilizes a complementary dielectric isolation process for matched NPN/PNP pairs, delivering discrete performance at IC prices. The parts are trimmed at the wafer stage to minimize THD and control-voltage feedthrough, requiring no further adjustment after packaging.
The 2180B is available in an 8-pin single-in-line (SIP) package and operates with a power supply voltage range of ±4 V to ±18 V. It is pin-compatible with the 2150-Series.
