Data Acquisition - ADCs/DACs - Special Purpose

The AK4384ET is a special purpose converter designed by AKM, a Japanese semiconductor company that specializes in audio devices. This product is part of the AKM Series G family, which is known for its high SNR and low THD performances. It is suitable for a variety of audio applications, including professional audio systems, digital recorders, audio mixers, and home theater systems.

The AK4384ET is a 12-bit sigma-delta A/D converter. It incorporates a one-channel differential voltage input, a signal pre-filtering stage and a multi-bit sigma-delta A/D converter. The AK4384ET operates at signal frequencies ranging from 50 Hz to 45 kHz and provides a greater dynamic range compared to conventional 8-bit and 10-bit A/D converters. The chip also includes a digital filter which allows the user to select either original or soft-limiting functions to reduce distortion.

The AK4384ET is designed for use in audio systems, where it can convert analog signals into digital signals with up to 12-bits of resolution. It is designed to work with applications that require wide dynamic range and low distortion, such as professional audio systems, digital recorders, audio mixers and home theater systems. This device is especially suitable for applications with high SNR and low THD performance requirements.

The AK4384ET\'s working principle is based on the sigma-delta modulation technique. This technique is used to convert the analog signal into a digital signal by representing the input signal as a series of pulses, which are then quantized by a multi-bit sigma-delta A/D converter. The sigma-delta modulation technique is based on a single-bit architecture with a digital filter to reduce distortion. The multi-bit sigma-delta A/D converter is comprised of an analog-to-digital converter and a digital filter which converts the analog input signal into a high-resolution digital signal.

The AK4384ET offers a number of features, including a fast conversion speed of 20MS/s with low distortion and low power consumption. It is also capable of a high sampling rate up to 192kHz with a wide dynamic range. Additionally, the device includes a one-channel differential voltage input, a signal pre-filtering stage, a low power consumption digital filter, and a temperature compensation circuit. Additionally, the chip includes a digital gain control to adjust the output level to any desired value.

The AK4384ET is an ideal choice for applications requiring a high SNR, low THD performance and wide dynamic range. It is suitable for use in professional audio systems, digital recorders, audio mixers, and home theater systems. The device is easy to use and provides excellent audio quality with minimal noise and distortion. Additionally, the AK4384ET has a wide operating temperature range and a low power consumption, making it ideal for a variety of audio applications.
