Overview
The Texas Instruments SRC4192IDBR is a high-end sample rate converter designed for professional and broadcast audio applications. This device combines a wide input-to-output sampling ratio with outstanding dynamic range and ultra-low distortion. The SRC4192 is a standalone, pin-programmed device that operates from a single 3.3-V power supply and features a separate digital I/O supply (VIO) that operates over the 1.65-V to 3.6-V range. It is available in a 28-pin SSOP package and is pin compatible with the AD1896.
