Wcd9341: Datasheet _verified_

Designing with the WCD9341 requires strict adherence to its electrical boundaries to prevent thermal runaway or audio distortion. -40°C to +85°C.

. It is widely used in professional repair for smartphones like the Samsung Galaxy S8, Note 8, and Note 9

According to the WCD9341 datasheet excerpts, this codec supports: wcd9341 datasheet

: It supports PCM audio up to 384-kHz/32-bit and offers native support for DSD (Direct Stream Digital) playback.

Native playback support for up to 384 kHz / 32-bit PCM audio and DSD64/DSD128 formats. Designing with the WCD9341 requires strict adherence to

Unlike standard codecs, the WCD9341 features a powerful integrated headphone amplifier. The datasheet typically lists:

Send register block: interface config, display timing, gamma LUT 6. Enable backlight with ramped PWM duty cycle 7. Set display on command It is widely used in professional repair for

Manufactured by Qualcomm, the WCD9341 is an Audio Codec IC (Integrated Circuit) designed to serve as the analog-to-digital and digital-to-analog interface for smartphones and other mobile devices. Frequently paired with high-end Qualcomm Snapdragon processors (such as the Snapdragon 845 and 855), this chip is responsible for the high-fidelity audio performance found in many flagship smartphones from the late 2010s.
