The PGA2311U/1K is a digitally-controlled stereo audio volume control IC designed by Texas Instruments for premium audio systems. It integrates a high-fidelity operational amplifier with extremely low distortion, low noise and wide dynamic range, making it suitable for audiophile-grade equipment and professional studio environments.
With the capability to directly drive 660-Ω loads without external buffering, the device simplifies PCB design while maintaining excellent audio performance. PGA2311U/1K is housed in a 16-SOIC (DW) package for easy integration into analog and mixed-signal audio circuits.
The internal high-performance op-amp ensures ultra-clean signal handling, making the PGA2311 suitable for audiophile and studio-grade equipment.
Supports fine-step digital attenuation with excellent channel matching, allowing precise stereo level balancing and quiet background operation.
Eliminates the need for a buffer amplifier in many applications, reducing component count and improving integration flexibility.
Engineered to maintain high signal integrity even in demanding audio chains, ensuring clear and detailed sound reproduction.
Integrated audio-optimized amplifier delivers low THD and high linearity across the full audio bandwidth.
Dual-channel design with synchronized digital control ensures perfectly matched left/right performance and smooth attenuation steps.
Directly drives 660-Ω loads, supporting long cable runs and balanced/unbalanced system interfaces used in studio installations.
