AK4363VF

The AK4363VF is a stereo CMOS D/A converter with an on-chip phase-locked loop (PLL) designed for digital video broadcast set-top boxes and DVD players. It uses a Delta-Sigma architecture to achieve high-quality audio conversion with single-ended outputs that include internal analog filtering, eliminating the need for external filters.

Key performance specifications include a resolution of 24 bits, a sampling range from 16 kHz to 96 kHz (including half-speed, normal-speed, and double-speed modes), a typical signal-to-noise ratio and dynamic range of 102 dB, and a signal-to-noise plus distortion ratio of 90 dB at 5V supply. Power dissipation is typically 80 mW.

The device supports multiple data input formats (LSB justified, MSB justified, I²S) and can be controlled via a 3-wire serial interface or I²C bus. The integrated PLL generates master clock frequencies from a 27 MHz reference clock, offering flexibility for various audio systems. Operating from a 2.7V to 5.5V supply, the AK4363VF is specified for -40°C to +85°C operation and is housed in a compact 24-pin VSOP package (24-LSSOP).
