PGA2310 SPI-Serial Stereo Audio Volume Control, dip-16

Description

The PGA2310 is a high-performance, stereo audio volume control designed for professional and high-end consumer audio systems.

Key technical aspects include:

• Voltage Handling: The ability to operate from ±15-V analog power supplies allows it to process input signals with large voltage swings, preserving the dynamic range of the overall signal path.

• Internal Amplification: It uses high-performance internal operational amplifier stages to achieve low noise and distortion.

• Drive Capability: It is capable of driving 600-Ω loads directly without the need for additional buffering.

• Control Interface: A three-wire serial interface allows connection to various host controllers and supports daisy-chaining multiple devices for multi-channel setups.
