1.3 DescriptionThe TWL6041isan audio codec witha high levelof integration providing analog audio codec functionsfor
portable applications, as shownin Figure 1-1. The device contains multiple audio analog inputs and
outputs,as wellas microphone biases and accessory detection. The deviceis connectedto the OMAP™ host processor througha proprietary PDM interface for audio data communication enabling partitioning consumption and performance. Multichannel audio datais multiplexedtoa single (PDML) and uplink (PDMUL). the with five PDM audio-input channels (DL0–DL4). channels multiplexedto stereo headphone (HSL, HFR), and earpiece (EAR) line outputs (AUXL, hasa low-power (LP) mode operating 32-kHzto playback time.
