ADAU1446YSTZ-3A Description

Short technical summary and product information.

The ADAU1446YSTZ-3A is a fully programmable SigmaDSP digital audio processor from Analog Devices, designed for enhanced sound processing in automotive and professional audio applications. It features a 172 MHz DSP core capable of executing 3584 instructions per sample at 48 kHz, with 4k parameter RAM and 8k data RAM.

 

The device includes a flexible audio routing matrix supporting 24-channel digital input and output, with up to 8 stereo asynchronous sample rate converters. Control is provided via I²C and SPI interfaces, and it supports serial and TDM I/O up to 192 kHz. An on-chip regulator generates 1.8V from the 3.3V supply.

 

Packaged in a 100-LQFP (14x14mm) surface mount package, the ADAU1446YSTZ-3A operates over a temperature range of -40°C to +105°C, making it suitable for automotive environments. Typical applications include automotive head units, navigation systems, rear-seat entertainment, and DSP amplifiers.
