The THAT2252L08-U features a voltage-controlled amplifier (VCA) that allows precise gain adjustment based on an external control voltage. This control voltage can be derived from a sidechain circuit, allowing the device to automatically adjust the gain based on the input signal's characteristics. The low distortion and wide dynamic range of the THAT2252 ensure that the processed audio signal remains clean and transparent, even under heavy gain reduction. The single or dual supply operation of the part provides flexibility in circuit design. This part is useful in applications where automation of audio level is required.
