The THAT Corporation 2181AS08-U is a high-performance, current-in/current-out voltage-controlled amplifier (VCA) IC. It features two opposing-polarity, voltage-sensitive control ports, enabling wide-range exponential control of gain and attenuation with minimal signal distortion.
Key specifications include a dynamic range exceeding 120 dB and a gain range greater than 130 dB. The device exhibits low total harmonic distortion, with typical values around 0.0025% for the 2181A grade. It also offers a wide gain-bandwidth of 20 MHz.
This VCA IC is designed for applications such as faders, panners, compressors, expanders, equalizers, filters, and oscillators. It is pin-compatible with the 2150-series and is available in an 8-pin SOIC surface-mount package.
In-circuit adjustment is required to achieve the guaranteed distortion and feedthrough performance. The device operates within a supply voltage range of ±4 V to ±18 V and has a typical supply current of 2.4 mA.
