Description

The AKM4384V is an IC chip designed for cost and performance based audio systems. Its modulator architecture offers a wide dynamic range while preserving linearity for improved THD+N performance. With a sampling rate ranging from 8kHz to 192kHz and a 24-bit word length, this part is ideal for a wide range of applications, including DVD-Audio. Its filters increase the performance for systems with excessive clock jitter. The AK4384V comes in a space-saving 16-pin TSSOP package.
