AK4397 is a high-performance 32-bit DAC that supports DVD-Audio's 192kHz sampling mode. It uses a newly developed advanced multi-bit method, which has a higher dynamic range and lower distortion. The built-in switch capacitor filter (SCF) can improve the accuracy degradation caused by clock jitter. The device supports 192kHz PCM input and DSD input, which is very suitable for DVD-Audio, SACD and other systems.
The document introduces the features of Asahi Kasei AK4543 codec, which is a 18-bit high performance codec compliant with Audio Codec ’97 Rev 2.1 requirements.
The AK2307/LV is an integrated LSI with PCM CODEC, Voice path control, MIC amplifier and Handset driver suitable for PBX/KTS digital key telephone, VoIP Telephone.
The AKD4393 is an evaluation board for AK4393, which is 96kHz sampling 24Bit ∆Σ DAC. The AKD4393 includes a LPF which can add differential analog outputs from the AK4393 and also has a digital interface with AKM’s wave generator using ROM data and AKM’s ADC evaluation boards. Therefore, it is easy to evaluate the AK4393.
The AK4386 is a 24-bit low voltage & low power stereo DAC that uses the Advanced Multi-Bit ∆Σ architecture. This architecture achieves DR=100dB at 3V operation. The AK4386 integrates a combination of SCF and CTF filters increasing performance for systems with excessive clock jitter. The AK4386 is suitable for the portable audio system like MP3 and the home audio systems like STB and TV, etc as low power and small package. The AK4386 is offered in a space saving 16pin TSSOP package.
ASAHI KASEI [AK93C45A/55A/65A/75A] DAM01E-01 is a 1K/2K/4K/8K-bit serial CMOS EEPROM with wide operating voltage range and low power consumption. It is ideal for low density data storage and offers high reliability and automation features.
The AK4635 is a 16-bit mono CODEC with Microphone-Amplifier, Speaker-Amplifier, and Video-Amplifier. It is suitable for moving picture devices such as digital cameras. The product features recording function, playback function, and video function, and supports Piezo Speaker. The AK4635 is housed in a space-saving 29-pin Wafer Level CSP 2.5mm x 3.0mm package.
AK4380 is a high performance audio product that supports sampling rates from 8kHz to 96kHz and features 128x oversampling and 24-bit 8x FIR digital filters.
AK4524 is a 24bit 96kHz audio codec produced by Asahi Kasei. The chip has an enhanced dual-bit architecture ADC with a wide dynamic range and uses SCF technology to achieve low output noise and high jitter tolerance. AK4524 also has an input PGA and is suitable for MD, DVTR systems and musical instruments.
The AK4351 is a high cost performance 18bit stereo DAC for low-end digital audio systems. The modulator in the AK4351 uses the new developed Advanced Multi Bit architecture with wide dynamic range. The analog outputs are filtered in the analog domain by a combination of SCF and CTF. Therefore, any external filters are not required. The SCF techniques also improve the loss of accuracy from clock jitter. Therefore, the AK4351 is suitable for the system like STB including PLL circuit. The AK4351 is available in very small 16pin TSSOP package, which reduces system space.
The AKD5393 is an audio 24-bit A/D converter from ASAHI KASEI that includes a full-differential input buffer circuit and a digital interface transmitter. It can be used with AKM's DAC evaluation boards or with CS8402 as a DIT to transmit optical output.
