WM8350GEB/V

Overview

The WM8350GEB/V is an integrated audio and power management subsystem designed for portable multimedia systems. It combines a stereo Hi-Fi CODEC with comprehensive power generation capabilities in a single chip. The audio section features DAC and ADC signal-to-noise ratios of 95dB at 48kHz, supporting sample rates from 8kHz to 48kHz. Power management includes six programmable DC-DC converters (four buck, two boost), four LDO regulators, and a current limit switch. It supports single-cell lithium battery charging via trickle or fast charge modes. The device operates on analog supplies of 2.5V to 3.6V and digital supplies of 1.71V to 3.6V, housed in a 129-ball TFBGA package.

Feature Summary

Integrated stereo CODEC with programmable headphone drivers and microphone preamplifiers
Comprehensive power management with multiple DC-DC buck/boost converters and LDOs
Single-cell lithium battery charger with thermal protection and status indication
On-chip real-time clock with wake-up alarm and watchdog timer

Applications

Portable audio and media players
Portable navigation devices
Systems powered by single-cell lithium batteries

Procurement Notes

Verify the component against official Wolfson Microelectronics datasheets to confirm pinout compatibility and electrical specifications. Ensure that the specific ordering suffix matches the required package variant and temperature range. Cross-reference the manufacturer's documentation for any updates regarding RoHS compliance or lifecycle status before finalizing procurement plans.

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 control over multiple voltage rails and battery charging profiles. Consider the integration level if minimizing external component count and board space are primary design constraints.

Part Context

The WM8350 belongs to the Wolfson AudioPlus series, which integrates audio codecs with power management functions. This family targets applications requiring efficient power usage and reduced bill-of-materials complexity. The device consolidates functions typically spread across separate audio and PMIC chips into a single 7x7mm BGA package.
