Overview
The WM8963ECSN/R is a low-power, stereo audio CODEC manufactured by Cirrus Logic. It integrates high-performance analog-to-digital and digital-to-analog converters with a microphone input and headphone driver. The device supports multiple digital audio interfaces including I2S, Left-Justified, DSP, and Philips I2S formats. It operates within a supply voltage range of 1.71 V to 3.6 V for the analog section and 1.05 V to 3.6 V for the digital section. The component features a 49-ball W-CSP package and supports sampling rates up to 48 kHz with 16-bit resolution.
Feature Summary
- Integrates stereo ADC and DAC with integrated headphone output drivers
- Supports multiple standard digital audio interface protocols
- Includes dedicated microphone bias and input stages
Applications
- Mobile multimedia devices requiring low-power audio processing
- Portable consumer electronics with stereo audio capabilities
- Embedded systems utilizing digital audio interfaces
Procurement Notes
Verify the specific suffix 'R' indicates reel packaging configuration as per manufacturer documentation. Confirm RoHS compliance status through official datasheets or environmental reports before integration. Ensure the 49-ball W-CSP footprint matches the target PCB layout constraints. Validate that the required supply voltages align with the system power design specifications.
Selection Notes
Select this component when a compact solution for stereo audio conversion is required. It is suitable for applications needing integrated headphone driving capability without external amplifiers. Consider the limited sampling rate support if higher fidelity audio standards are necessary. Evaluate the package size against available board space in portable designs.
Part Context
This part belongs to the Cirrus Logic WM8963 series of audio CODECs. It is designed for mobile and multimedia applications where power efficiency and small form factor are critical. The ECSN/R designation specifies the package type and tape-and-reel delivery method.
Replacement Considerations
Check for direct pin-compatible alternatives within the Cirrus Logic portfolio. Verify functional equivalence regarding supported interfaces and power requirements. Consult manufacturer discontinuation notices for long-term availability assurance.
