ADAU1462/ADAU1466

Data Sheet

GENERAL DESCRIPTION

The ADAU1462/ADAU1466 are automotive qualified audio

processors that far exceed the digital signal processing

capabilities of earlier SigmaDSP® devices. They are pin and

ADAU1450/ADAU1451/ADAU1452 SigmaDSP processors.

The restructured hardware architecture is optimized for

efficient audio processing. The audio processing algorithms

support a seamless combination of stream processing (sample

by sample), multirate processing, and block processing

paradigms. The SigmaStudio™ graphical programming tool

enables the creation of signal processing flows that are

interactive, intuitive, and powerful. The enhanced digital signal

processor (DSP) core architecture enables some types of audio

processing algorithms to be executed using significantly fewer

instructions than were required on previous SigmaDSP

generations, leading to vastly improved code efficiency.

Dedicated decimation filters can decode the pulse code

modulation (PDM) output of up to four MEMS microphones.

Independent slave and master I²C/SPI control ports allow the

ADAU1462/ADAU1466 to be programmed and controlled by

an external master device such as a microcontroller, and to

program and control slave peripherals directly. Self boot

functionality and the master control port enable complex

standalone systems.

The power efficient DSP core can execute at high computational

loads while consuming only a few hundred milliwatts (mW) in

typical conditions. This relatively low power consumption and

small footprint make the ADAU1462/ADAU1466 ideal

replacements for large, general-purpose DSPs that consume

more power at the same processing load.

Note that throughout this data sheet, multifunction pins, such

as SS_M/MP0, are referred to either by the entire pin name or

by a single function of the pin, for example, MP0, when only

that function is relevant.

The 1.2 V, 32-bit DSP core can run at frequencies of up to

294.912 MHz and execute up to 6144 SIMD instructions per

sample at the standard sample rate of 48 kHz. Powerful clock

generator hardware, including a flexible phase-locked loop

(PLL) with multiple fractional integer outputs, supports all

industry standard audio sample rates. Nonstandard rates over a

wide range can generate up to 15 sample rates simultaneously.

These clock generators, along with the on board asynchronous

sample rate converters (ASRCs) and a flexible hardware audio

routing matrix, make the ADAU1462/ADAU1466 ideal audio

hubs that greatly simplify the design of complex multirate audio

systems.

DIFFERENCES BETWEEN THE ADAU1466 AND

ADAU1462

The three variants of this device are differentiated by memory

and DSP core frequency. A detailed summary of the differences
