ADAU1462WBCPZ300RL

Overview

The ADAU1462WBCPZ300RL is an automotive-qualified, fully programmable SigmaDSP digital audio processor. It features a 32-bit DSP core operating at up to 294.912 MHz on a 1.2 V supply. The device provides 48 kWords of data memory and 16 kWords of program memory. It includes four serial input ports, four serial output ports, and supports 48-channel, 32-bit digital I/O up to 192 kHz sample rates. Key interfaces include I2C, SPI, S/PDIF, and PDM microphone inputs. The component is housed in a 72-lead LFCSP package and operates within a temperature range of -40°C to +105°C.

Feature Summary

• Automotive qualified with AEC-Q100 certification
• 32-bit SigmaDSP core running at 294.912 MHz
• 48 kWords data memory and 16 kWords program memory
• Integrated asynchronous sample rate converters (ASRCs) with 139 dB dynamic range

Applications

• Automotive audio processing head units
• Rear seat entertainment systems
• Trunk amplifiers

Procurement Notes

Verify the specific suffix '300' indicates the 294.912 MHz core frequency variant. Confirm the 'RL' suffix corresponds to reel packaging. Ensure the LFCSP-72 package dimensions match the target PCB footprint. Check for RoHS compliance documentation if required by local regulations.

Selection Notes

Select this model over the ADAU1466 when 48 kWords of data memory is sufficient, as the ADAU1466 offers 80 kWords. Both share the same pinout and register compatibility. Consider the ADAU1462WBCPZ150 if a lower core frequency of 147.456 MHz meets the processing requirements.

Part Context

This component belongs to the Analog Devices SigmaDSP family, specifically designed for high-performance audio processing. It is pin and register compatible with the ADAU1450/1451/1452 series, facilitating upgrades from previous generations while offering enhanced computational efficiency and flexible clock generation capabilities.

Replacement Considerations

ADAU1466WBCPZ300RL: Offers increased memory (80 kWords data, 24 kWords program) with identical pinout and functionality.
