Product details
Overview
ADAU1462WBCPZ150RL from Analog Devices is an automotive-qualified 32-bit SigmaDSP audio processor with a 147.456 MHz core, 48 kWords of data RAM, 16 kWords of program memory, and support for up to 48-channel 192 kHz digital I/O. It integrates 8 stereo ASRCs (139 dB DR), S/PDIF I/O, four PDM microphone inputs, and self-boot capability via EEPROM-used in trunk amplifiers and distributed automotive audio systems.
For engineers reviewing the ADAU1462WBCPZ150RL datasheet, ADAU1462WBCPZ150RL pinout, ADAU1462WBCPZ150RL application, or ADAU1462WBCPZ150RL equivalent, key selection criteria include its 147.456 MHz DSP core frequency, 48 kWords data RAM capacity, −40°C to +105°C operating range, and LFCSP-72 package compatibility with automotive head unit signal routing and multirate clock domain management.
Technical Context
The ADAU1462WBCPZ150RL implements a restructured SigmaDSP architecture optimized for stream, multirate, and block audio processing. Its integer PLL and flexible clock generators produce up to 15 simultaneous sample rates, while dedicated decimation filters decode PDM signals from four MEMS microphones.
It features dual I²C/SPI control ports (slave and master), enabling external microcontroller programming and direct peripheral control. The on-chip 1.2 V regulator derives DVDD from 3.3 V AVDD, and the integrated die temperature sensor supports thermal monitoring in sealed automotive enclosures.

FAQ
What is the maximum sample rate supported by ADAU1462WBCPZ150RL for its serial audio ports?
ADAU1462WBCPZ150RL supports digital audio I/O up to 192 kHz across its 48-channel TDM interface. This applies to all serial input and output ports (SDATA_IN0–3 and SDATA_OUT0–3), with flexible format support for I²S, left/right justified, PCM, and TDM configurations. The S/PDIF transmitter and receiver also operate up to 192 kHz, as confirmed in Table 10 of the Rev. C datasheet.
Does ADAU1462WBCPZ150RL include an integrated voltage regulator, and what does it supply?
Yes, ADAU1462WBCPZ150RL includes an on-chip regulator that generates 1.2 V DVDD from a 3.3 V AVDD supply. This regulator supports up to 800 mA load and powers the 32-bit SigmaDSP core, ASRCs, and signal routing logic-reducing external power management components in automotive amplifier designs.
How many asynchronous sample rate converters (ASRCs) does ADAU1462WBCPZ150RL integrate, and what is their dynamic range?
ADAU1462WBCPZ150RL integrates eight stereo (16-channel) asynchronous sample rate converters, each delivering 139 dB A-weighted dynamic range (20 Hz–20 kHz). These ASRCs enable seamless integration of audio sources with mismatched sample rates-such as Bluetooth (44.1 kHz) and USB audio (48 kHz)-without external clock domain isolation hardware.
Can ADAU1462WBCPZ150RL operate without an external microcontroller?
Yes, ADAU1462WBCPZ150RL supports standalone operation via self-boot from serial EEPROM. When configured with valid firmware and initialization parameters stored in external EEPROM, the device initializes and executes audio processing autonomously-making it suitable for cost-sensitive automotive amplifier modules where MCU integration is unnecessary.
What is the function of the MP0–MP13 pins on ADAU1462WBCPZ150RL, and what is their maximum switching rate?
The MP0–MP13 pins on ADAU1462WBCPZ150RL are multipurpose I/Os configurable as GPIOs, PWM outputs, interrupt inputs, or auxiliary control signals. Their maximum switching rate is 24.576 MHz when used as general-purpose outputs, and input latency is bounded by 6144 × tCORE (equal to one audio sample period at 48 kHz with full instruction budget), as specified in Table 9 of the Rev. C datasheet.
