The AD604AN from Analog Devices Inc. is a state-of-the-art dual-channel, ultralow noise, linear-in-dB variable gain amplifier (VGA) designed to meet the stringent requirements of communication, instrumentation, and professional audio applications. This high-performance component is engineered to provide precise gain control, high bandwidth, and low distortion, making it an ideal choice for a wide range of applications.

Key Features

• Variable Gain Range: The AD604AN offers an outstanding gain range from -11 dB to +31 dB, which is adjustable in linear dB steps through a differential input control voltage, providing users with fine-grained control over amplification levels.
• Ultralow Noise Performance: With a focus on maintaining signal integrity, this VGA exhibits an exceptional noise figure of just 2.6 dB at maximum gain, ensuring that the signal-to-noise ratio is preserved even at high amplification levels.
• Dual Channels: The dual-channel configuration allows for simultaneous processing of two independent signals, or for differential signal processing, which is crucial for applications requiring balanced audio or high common-mode rejection.
• Wide Bandwidth: The device features a 3-dB bandwidth of 90 MHz, delivering fast response times and the ability to handle a broad range of frequencies with ease.
• Low Distortion: The AD604AN is designed to minimize distortion, with a Total Harmonic Distortion (THD) of -75 dB, making it suitable for high-fidelity audio and precision instrumentation applications.
