Overview
The WM8778SEDS/RV is a stereo audio CODEC manufactured by Cirrus Logic, housed in a 28-pin SSOP package. It features a single ADC and a single DAC with 24-bit resolution and sampling rates up to 192 kHz. The device operates on a supply voltage ranging from 2.7 V to 5.5 V and supports Serial 2-Wire or 3-Wire (SPI) interfaces. Signal-to-noise ratios are specified at 102 dB for the ADC and 108 dB for the DAC. The component functions within an operating temperature range of -25°C to +85°C.
Feature Summary
- Stereo audio conversion with high-resolution digital processing capabilities
- Flexible serial control interface supporting standard communication protocols
- Integrated sigma-delta modulation for analog signal handling
Applications
- Recordable media devices requiring high-fidelity audio capture
- Professional audio recording equipment
- Digital audio workstations and studio interfaces
Procurement Notes
Verify current availability status as this component may be subject to end-of-life restrictions. Confirm that the specific suffix matches the required package and tape/reel specifications for your manufacturing process. Ensure compliance with RoHS directives and humidity sensitivity levels before procurement.
Selection Notes
Select this component when a combined stereo codec solution is required rather than separate ADC and DAC units. Verify that the system architecture can accommodate the 2.7 V to 5.5 V power supply range. Ensure the host processor supports the necessary serial interface protocol for configuration and data transfer.
Part Context
This part belongs to the WM8778 series of audio CODECs from Cirrus Logic. It is designed for applications demanding high dynamic range and low distortion in stereo audio paths. The SSOP-28 package provides a compact footprint suitable for space-constrained electronic designs.
Replacement Considerations
Check for official obsolescence notifications. Potential substitutes within the same family should be evaluated based on pin compatibility and electrical specifications. No direct public substitute part numbers are confirmed.
