Frequently Asked Questions
What is the channel separation of the PGA2311UA?
The PGA2311UA achieves 130 dB channel separation between its two stereo channels, making it well-suited for high-fidelity audio applications where crosstalk must be minimized, such as professional mixing consoles and audiophile preamplifiers.
How is the PGA2311UA controlled?
The PGA2311UA uses a 3-wire SPI serial interface for digital control, allowing microcontrollers or DSPs to set the gain/attenuation levels independently on each of its two channels with fine resolution across the full volume range.
What are typical applications for the PGA2311UA?
Typical applications include professional audio preamplifiers, home theater AV receivers, studio mixing equipment, automotive infotainment systems, and DSP-based audio processors that require precise, low-noise stereo volume control.
What package is the PGA2311UA available in?
The PGA2311UA is available in a 16-pin SOIC (Small Outline IC) package, designated R-PDSO-G16, which is compatible with standard SMT assembly processes and suitable for compact PCB designs.
