AK7738VQ

Digital Signal Processor Dsp Overview

The AK7738VQ is a floating-point digital signal processor manufactured by Asahi Kasei Microdevices (AKM). It integrates five 24-bit analog-to-digital converters, four 24-bit digital-to-analog converters, and eight sample rate converters. The device operates with a clock rate of 48kHz and utilizes I²C and SPI interfaces for control. It features 169.5kB of on-chip RAM and functions within a voltage range of 3.30V for both I/O and core logic. The component is designed for surface mount installation in a 64-LQFP package measuring 10x10 mm, supporting an operating temperature range from -40°C to 85°C.
