Overview
The WM8351CGEB/RV is an integrated audio and power management subsystem designed for portable multimedia systems. It combines a stereo Hi-Fi CODEC with comprehensive power management capabilities in a single chip. The audio section features DAC and ADC signal-to-noise ratios of 95dB (A-weighted at 48kHz) and supports sample rates from 8kHz to 48kHz. Power generation includes one DC-DC buck converter rated up to 1A, two additional buck converters up to 500mA each, one boost converter (5V-20V), and four LDO regulators (0.9V-3.3V). It incorporates a single-cell lithium battery charger, LED drivers, and a real-time clock.
Feature Summary
- Integrated stereo Hi-Fi CODEC with programmable on-chip amplifiers for direct microphone and headphone connections
- Comprehensive power management with multiple DC-DC converters, LDOs, and autonomous power source selection
- Single-cell lithium battery charger with thermal protection and programmable charge parameters
- Built-in real-time clock with wake-up alarm and watchdog timer for system monitoring
Applications
- Portable Audio and Media players
- Portable Navigation Devices
- Systems powered by single-cell lithium batteries
Procurement Notes
Verify the specific ordering suffix 'RV' against the manufacturer's current documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with the required control interface protocols before procurement. Confirm that the component meets all necessary environmental standards for the intended deployment environment.
Selection Notes
Select this component when a unified solution for high-fidelity audio processing and complex power sequencing is required. It is suitable for designs needing independent power control for various subsystems. Consider the BGA package constraints during PCB layout. Verify that the available GPIO count and LED driver capabilities meet the specific peripheral requirements of the target application.
Part Context
The WM8351 belongs to the Wolfson AudioPlus series of audio and power management solutions. It is manufactured by Cirrus Logic (formerly Wolfson Microelectronics). This part integrates functions typically requiring multiple discrete components into a single 7x7mm BGA package, reducing board space and simplifying design complexity for portable devices.
Replacement Considerations
Consult official substitution guides for compatible alternatives within the same product family or from other manufacturers offering similar integrated audio and PMIC solutions.
