The PGA2311UA from Texas Instruments is a high-performance, digitally-controlled analog stereo audio volume control IC. Designed for professional and high-end consumer audio applications, it utilizes an internal operational amplifier to achieve low noise and distortion, with a THD+N as low as 0.0002% at 1 kHz (A-Grade).
This IC features two independent audio channels with a wide gain and attenuation range from +31.5 dB to -95.5 dB in 0.5-dB steps. It includes essential functions like zero-crossing detection and a mute function. The device operates with analog supply voltages of ±5V and a digital supply of +5V, and can drive 660-Ω loads directly.
The PGA2311UA communicates via a 3-wire serial control interface (SPI), allowing for easy integration with various host controllers and support for daisy-chaining multiple devices. It is available in a 16-SOIC surface-mount package and operates within a temperature range of -40°C to 85°C.
Key specifications include a dynamic range of 120 dB and low interchannel crosstalk of -130 dBFS. Its applications span automotive audio, musical instruments, and professional audio equipment.
