AK4637EN Application Field and Working Principle

Introduction

The AK4637EN is a CODEC that was developed by Asahi Kasei Microsystems Co., Ltd. It is an 8-bit A/D and D/A converter with a 2.5V supply voltage, and is suitable for a wide range of applications that require high quality audio performance. The AK4637EN is ideal for applications such as CD-ROMs, portable audio players and multi-channel audio systems.

Applications

The primary application of the AK4637EN is in portable audio and video players. Its low power consumption and small package size make it well-suited for use in mobile devices. The device has two analog microphone inputs as well as a line input, allowing it to be used for voice recognition or multi-channel recording. The AK4637EN also has a headphone amplifier and a signal processor, making it ideal for digital audio players.

Features

The AK4637EN has a sampling rate of up to 24-bit/96 kHz and a signal-to-noise ratio of up to 90 dB. It has an integrated line input and two stereo analog microphone inputs, as well as a headphone amplifier. The device also has a signal processor, which allows it to be used for audio signal processing and sound synthesis. The AK4637EN also has a number of features that make it well-suited for low-power applications. These include a low standby current, a smart power-down mode, and a Fast Wake Up mode, which allows the device to wake up from sleep mode in seconds.

Working Principle

The AK4637EN is an 8-bit A/D and D/A converter with a 2.5V supply voltage. It has two analog microphone inputs and a line input, as well as a headphone amplifier and a signal processor. The device operates by converting incoming analog signals into digital signals, and then converting the digital signals back into analog signals for playback.The AK4637EN uses a Delta-Sigma Modulator for A/D conversion, allowing it to achieve a high signal-to-noise ratio. The device also features a proprietary Time Interleaved Analog-to-Digital Conversion (TIADC) technology, which helps to reduce power consumption and increase accuracy.For D/A conversion, the device uses a Digital to Analogue Converter (DAC). The DAC converts the digital signals back into analog signals for playback.

Conclusion

The AK4637EN is an 8-bit A/D and D/A converter with a 2.5V supply voltage, and is suitable for a wide range of applications that require high quality audio performance. It is ideal for applications such as CD-ROMs, portable audio players and multi-channel audio systems. The device has a number of features that make it well-suited for low-power applications. These include a low standby current, a smart power-down mode, and a Fast Wake Up mode. The AK4637EN is an ideal choice for applications that require excellent audio quality and power efficiency.
