Description

The AK4386VT-E2 is a 24-bit low voltage and low power stereo DAC (Digital-to-Analog Converter) that belongs to the IC Chips product category. It utilizes the Advanced Multi-Bit DS architecture, which allows for a dynamic range of 100dB at a 3V operation. The AK4386VT-E2 incorporates a combination of SCF (Switched-Capacitor Filter) and CTF (Continuous-Time Filter) filters to improve performance in systems with excessive clock jitter. This DAC is suitable for various applications, including portable audio systems like MP3 players and home audio systems such as STBs (Set-Top Boxes) and TVs. It offers low power consumption and comes in a compact 16-pin TSSOP (Thin Shrink Small Outline Package) package.
