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.
The AK4386 from AKM (Asahi Kasei Microsystems) is a 24‑bit low‑voltage, low‑power stereo DAC that uses the Advanced Multi‑Bit (AZ) architecture. It offers a dynamic range of 100 dB, supports sampling rates from 8 kHz to 96 kHz, and is supplied in a compact 16‑pin TSSOP package.
The datasheet provides detailed electrical specifications, pin functions, absolute maximum ratings, recommended operating conditions, and filter characteristics. It also includes timing diagrams, package dimensions, and marking information for proper integration into portable audio and home audio systems.
