概要

Description

The ADAU1701JSTZ-RL is a SigmaDSP digital signal processor from Analog Devices, designed for audio processing applications. It features a 28-/56-bit DSP core, 24-bit ADCs/DACs, and supports sample rates up to 48 kHz.
Key features:
- Flexible audio routing with mixers, filters, and dynamics processing.
- On-chip memory (12 KB RAM, 4 KB flash) for storing programs.
- I²C/SPI control interface and SigmaStudio GUI for easy configuration.
- Low power consumption (~50 mW), suitable for portable devices.
Applications include soundbars, automotive audio, effects processors, and home audio systems. The JSTZ-RL variant comes in a 48-lead LQFP package and is RoHS-compliant.
For development, Analog Devices provides SigmaStudio, a drag-and-drop tool for designing DSP algorithms without coding.
