Linear - Amplifiers - Audio AS3422 (Equivalent Input Flip-Poled) is an incredibly unique type of audio amplifier. This type of amplifier offers some very unique capabilities and characteristics, making it an invaluable tool in audio production, broadcast and studio engineering, and countless other professional and consumer applications. Such as applying active sound-masking to large multi-room audio systems, basebands, and many other applications that require powerful audio amplification.The AS3422-EQFP-500 is an audio amplifier with a specification of 500 mA @ 8 VDC. This device is a two-stage, class AB, push-pull amplifier featuring a low-voltage differential signal (LVDS) input. This allows for a maximum differential swinging level of 1.5 volts and with its gain set to 11.4dB, it can achieve a power output of 4 W typical.The AS3422-EQFP-500 offers a wide range of features, ranging from high power efficiency and very low distortion, to a current-mode gain stage and adjustable gain control. The amplifier also features an inbuilt amplifier protector, which protects against overloads and other instabilities that might otherwise cause damage to the amplifier.The AS3422-EQFP-500 provides a versatile power amplifier design, making it suitable for a variety of professional and consumer applications. Its 300kHz cutoff frequency and low-level input voltage make it a perfect choice for applications that require low-level signal quality and high-frequency response.The AS3422-EQFP-500’s audio frequency response is tailored for medium-density applications (typically electro-acoustic, orchestral and hi-fi installations) that demand precise reproduction of signal distortion and signal bandwidth from low-end to high frequencies.The AS3422-EQFP-500 also offers an adjustable bass compensation feature, which allows for precise bass tuning in audio systems. This feature helps create natural sounding and balanced sound output, as well as more defined and crisp mid-bass and low-end sounds. The AS3422-EQFP-500 also includes a low noise and output crossover mechanism, which allows for high quality reproduction of all audible frequencies.The AS3422-EQFP-500 also features a large number of protection features. This includes the “Soft-Start” protection, which prevents excessive current surges on powering up, as well as an adjustable protection point for thermal stability and protection from short-circuits and other overloads.The AS3422-EQFP-500 also offers users two main external control interfaces: the “gain switching” feature, which allows users to select from any of three different gains and the “soft-sink” feature, which allows the user to select from two different types of power output. These two features allow users to customize the audio output for their specific needs.Overall, the AS3422-EQFP-500 is an incredibly versatile and powerful audio amplifier, suitable for a wide range of applications. Its adjustable gain, low-level input voltage, and wide range of protection features make it a must-have for anyone looking to maximize sound quality and ensure a safe and reliable audio system.
