AK5355VT-E2 Audio ADC

Updated: 2026-07-21

Overview

The AK5355VT-E2 is a high-performance stereo analog-to-digital converter (ADC) developed by Asahi Kasei Microdevices (AKM). It is widely used in professional audio equipment, digital mixing consoles, and high-end consumer electronics due to its superior audio quality and compact footprint. This IC integrates advanced delta-sigma modulation technology, offering a high signal-to-noise ratio (SNR) and low total harmonic distortion (THD), making it suitable for applications requiring precise audio signal conversion. Its low power consumption and small package size also make it ideal for portable devices.

Structure and Working Principle

The AK5355VT-E2 operates on a delta-sigma modulation principle, which oversamples the input analog signal and converts it into a high-resolution digital output. It includes built-in digital filters to minimize aliasing and noise. The IC features a differential input structure, reducing common-mode noise and improving signal integrity. It supports various sampling rates, typically ranging from 8 kHz to 48 kHz, and interfaces seamlessly with digital signal processors (DSPs) and microcontrollers via serial data output.

Key Features

The AK5355VT-E2 stands out for its high SNR (typically 105 dB) and low THD (less than 0.003%), ensuring clear and accurate audio reproduction. Its power supply voltage ranges from 2.7V to 3.6V, making it energy-efficient. Additionally, the IC supports master and slave clock modes, providing flexibility in system integration. Its compact SSOP-20 package allows for space-saving PCB designs, which is crucial for portable and embedded applications.

Application Areas

The AK5355VT-E2 is commonly used in professional audio equipment such as digital mixers, audio interfaces, and studio recorders. It is also found in consumer electronics like high-end headphones, soundbars, and home theater systems. Industrial applications include voice recognition systems, telecommunication devices, and automotive audio systems, where high-fidelity audio conversion is essential.

Maintenance and Precautions

To ensure optimal performance, the AK5355VT-E2 should be handled with ESD precautions during installation and soldering. Proper PCB layout techniques, such as grounding and shielding, are critical to minimizing noise interference. Avoid exposing the IC to excessive heat or moisture, as these conditions can degrade performance. Regular testing and calibration of the audio system can help maintain long-term reliability.

B2B Procurement Guide

When procuring the AK5355VT-E2, verify the supplier's authenticity to avoid counterfeit components. Bulk purchases (typically 1,000+ units) often qualify for discounted pricing. Consider lead times, as specialty ICs may have longer delivery periods. Evaluate datasheets and application notes to ensure compatibility with your system design. For prototyping, sample quantities may be available from authorized distributors.
