The LM4549BVHX/NOPB from Texas Instruments is an audio codec IC for PC systems, fully compliant with the AC '97 Rev 2.1 architecture. Utilizing 18-bit sigma-delta ADCs and DACs, it provides a dynamic range of 90 dB for ADCs and 89 dB for DACs. This device is designed to deliver a high-quality audio path and handle all analog functions within a PC audio system.
Key features include full-duplex stereo ADCs and DACs, along with analog mixers supporting multiple stereo and mono inputs. Each mixer input offers separate gain, attenuation, and mute control. The mixers drive one mono and two stereo outputs, each with attenuation and mute control. The device supports high-quality sample rate conversion from 4 kHz to 48 kHz in 1-Hz increments and includes Texas Instruments' 3D Sound stereo enhancement circuitry.
Operating within a temperature range of -40°C to 85°C, the LM4549BVHX/NOPB is available in a 48-LQFP package suitable for surface mounting. It supports digital 3.3-V and 5-V supply options and features advanced power management, including External Amplifier Power Down (EAPD) control. The codec also provides PC-Beep passthrough to the line out during initialization or cold reset.
