(wlp 3.09 - please refer to the latest windows logo program requirements from microsoft.) the codec does not support power limiting. headphone performance will degr ade if more than one port is driving a 32 ohm load. 2.17. btl amplifier an integrated class-d stereo btl amplifier is pr ovided to directly drive 4 ohm speakers (2w @ 4.75v) or 8 ohm speakers (1w @ 4.75v). no external filter is needed for cable runs of 18? or less. an internal dc blocking filter prevents distorti on when the audio source has dc content, and pre- vents unintentional power consumption when paus ing audio playback. the amplifier may be con- trolled using the eapd pi n (see eapd section.) using a vendor specific verb, the btl amplifier may be configured to support a mono speaker con- nected to the l +/- pins. in this mode, the left a nd right audio is mixed and sent to the left output only. the right channel is turned off to conserve power. maximum gain for the btl amplifier is programmab le. the following 4 gain se ttings relative to a nominal line output are desired: +6.5db, +9.5db, +14.5db, +16.5db. absolute gain may vary and the suggested accura cy is +/-1.5db. this gain is exposed in a vendor specific widge t and is intended to mimic the pin programmable gain implemented in discrete btl amplifiers commonly used in notebook computers. the btl amplifier includes thermal management circuitry. when the codec reaches a temperature of about 140 degrees, the output amplitude of the btl amp is gradually lowered until the tempera- ture falls below 140. all other functions will remain active if the btl amplifier is shut down due to die temperature. 2.18. btl amplifie r high-pass filter for mobile applications, speakers are often in capable of reproducing low frequency audio and unable to handle the maximum output power of th e btl amplifier. a high-pass filter is implemented in the btl output path to reduce the amount of lo w frequency energy reaching speakers attached to the btl amplifier. this can prevent speaker failure. www.datasheet.net/ datasheet pdf - http://www..co.kr/
