AKM’s high performance and low power audio CODECs are designed for wide range of applications such as portable audio, home audio, and automotive. AKM’s audio CODECs deliver the best sound quality along with high integration and design flexibility.

AK4954AEN: 32-bit, fs=96kHz Low-Power Stereo CODEC with MIC/HP/SPK-Amplifiers

The AK4954AEN is a low-power 32-bit stereo CODEC with a high performance stereo microphone amplifier, a ground-referenced stereo headphone amplifier and a mono speaker amplifier. The speaker amplifier operates at 0.9 to 5.5V, enabling a direct drive from the batteries. The 32-bit A/D and D/A converters deliver a high quality sound with low power consumption that is the best fit for portable audio applications. 

 

New AKE4951AEN: 24-bit Stereo CODEC with MIC/HP/SPK-Amplifiers&LDO

The input circuits include a microphone amplifier, an automatic wind noise reduction filter of the proprietary algorithms and a high performance digital ALC (automatic level control) circuit, therefore the AK4951AEN can record with high-quality sound regardless of whether indoors or outdoors. In addition, the output circuits include a cap-less headphone amplifier and a speaker amplifier with 1W output power. It is suitable for audio and voice products as well as portable applications with recording/playback function.

 

AK4958: 24-bit Stereo CODEC with MIC/HP/SPK-Amplifiers&LDO

The input circuits include a microphone amplifier, an automatic wind noise reduction filter of the proprietary algorithms and a high performance digital ALC (automatic level control) circuit, therefore the AK4958 can record with high-quality sound regardless of whether indoors or outdoors. In addition, the output circuits include a speaker amplifier. A one channel composite In/Out video amplifer is also integrated. It is suitable for audio and voice products as well as portable applications with recording/playback function.

 

New AK4637EN: 24-bit Mono CODEC with MIC/SPK-Amplifiers&LDO

The AK4637 is ideal for IoT (internet of things) or portable devices requiring a low-power audio 24-bit monaural CODEC with a microphone amplifier, speaker amplifier with built in regulators. The input circuits include a “Wind Noise Reduction Filter”, "5-band Notch Filter” that allow for the removal of specific system tones/noises and a “Digital Automatic Level Control (ALC) Circuit” to optimizes recording levels, therefore the AK4637 can record with high-quality sound regardless of whether indoors or outdoors. In addition, the output circuits include a speaker amplifier with 1W output power.

  

New AK4558EN: 24-bit, fs216kHz Audio CODEC with PLL

The AK4558 is a low voltage 32bit 216kHz CODEC for high performance battery powered digital audio subsystems. An internal circuit includes newly developed 32-bit Digital Filter achieving short group delay and high quality sound. In addition, "OSR-Doubler" technology is newly adopted, making the AK4558 capable of supporting wide range signals and achieving low out- of band noise while realizing low power consumption. The AK4458 is ideal for a wide range of applications that demands high sound quality includinng Electronic musical instruments and Audio Interfaces.

 

AK4616VQ: 3-in/5-out Audio CODEC with MIC Amplifier

The AK4616VQ is a multi-channel audio CODEC designed for car audio systems.The AK4616VQ integrates 4:1 stereo input selector in front of a 99dB stereo ADC, a mono microphone amplifier in front of a mono ADC for a guidance sound, and a 5-channel 105dB DAC along with a full-range digital volume control in a single chip.
