LM4548A Product details

Description

The LM4548A is an audio codec for PC systems which is fully PC98 compliant and performs the analog intensive functions of the AC ’97 Rev 2 architecture.

Features

full duplex stereo ADCs and DACs and analog mixers with access to 4 stereo and 4 mono inputs. Each mixer input has separate gain, attenuation and mute control and the mixers drive 1 mono and 2 stereo outputs, each with attenuation and mute control. The LM4548A 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.
