AKM Semiconductor, Inc. Data Acquisition - Data Acquisition - ADCs/DACs - Special Purpose - AK4393VF AK4393VF

The AK4393VF is a high-performance stereo digital-to-analog converter (DAC) designed for audio applications, supporting a sampling rate of up to 108kHz and featuring a 24-bit digital filter. It utilizes an advanced multi-bit architecture for its ,àÜO£ modulator, which enhances dynamic range while maintaining low distortion levels comparable to traditional single-bit systems. The device offers full differential outputs, making it suitable for high-end audio applications. Key specifications include a total harmonic distortion plus noise (THD+N) of -100dB and a dynamic range (DR) and signal-to-noise ratio (S/N) of 120dB. The AK4393VF operates with an analog supply voltage of 5V and a digital supply voltage of 3.3V, facilitating easy integration with 3.3V logic ICs. It features a high tolerance to clock jitter and includes digital de-emphasis for various sampling rates (32, 44.1, 48, and 96kHz). The device is packaged in a compact 28-pin VSOP format, making it suitable for space-constrained designs.
