The LM4546BVHX from Texas Instruments is an 18-bit audio codec designed for PC systems, fully compliant with AC '97 Rev 2.1 architecture. It utilizes Sigma-Delta ADCs and DACs to provide a dynamic range of 90 dB for ADCs and 89 dB for DACs. The device supports high-quality sample rate conversion from 4 kHz to 48 kHz and includes Texas Instruments' 3D Sound stereo enhancement circuitry.
This audio codec features full duplex stereo ADCs and DACs, along with analog mixers that allow access to multiple inputs. Each mixer input offers independent gain, attenuation, and mute control. The LM4546BVHX supports advanced power management and offers digital supply options of 3.3V and 5V. Its extended temperature range of -40°C to 85°C makes it suitable for various non-PC codec applications as well.
The LM4546BVHX is packaged in a 48-LQFP (7x7) and is designed for surface mount applications. It operates within a voltage range of 4.2V to 5.5V. The serial data interface facilitates communication within the system.
The LM4546BVHX is an Audio, AC '97 type codec.
The resolution of the ADCs and DACs is 18 bits.
The operating temperature range is -40°C to 85°C.
The RoHS status is RoHS3 Compliant.
The MSL rating is 1 Unlimited.
The package type is 48-LQFP.
