LM4546B Product details

Description

The LM4546B is an audio codec for PC systems which is fully PC99 compliant and performs the analog intensive functions of the AC ’97 Rev 2.1 architecture..

Features

full duplex stereo ADCs and DACs and analog mixers with access to 2 stereo and 2 mono inputs. Each mixer input has separate gain, attenuation and mute control and the mixers drive 1 mono and 1 stereo output, each with attenuation and mute control. The LM4546B supports National’s 3D Sound stereo enhancement and a comprehensive sample rate conversion capability. The sample rate for the ADCs and DACs can be programmed separately with a resolution of 1 Hz to convert any rate in the range 4 kHz.
