Description

The AK4386 is a 24bit low voltage & low power stereo DAC. It uses the Advanced Multi-Bit DS architecture, this architecture achieves DR=100dB at 3V operation. The product 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.
