Frequently Asked Questions
What are the key specifications of the PGA2311U?
The PGA2311U is a 2-channel stereo audio volume control IC featuring 130 dB channel separation, a gain range of -95.5 dB to +31.5 dB in 0.5 dB steps, SPI-compatible serial interface, and a ±15V supply voltage. It is housed in a 16-pin SOIC package.
What applications is the PGA2311U suitable for?
The PGA2311U is designed for professional audio equipment, home theater systems, preamplifiers, mixing consoles, and automotive audio head units. Its high channel separation and low noise performance make it ideal for high-fidelity stereo audio volume control applications.
How does the PGA2311U interface with a microcontroller?
The PGA2311U uses a 3-wire SPI-compatible serial interface (SDI, CLK, CS) to communicate with a microcontroller. Volume levels for both channels are set by sending 16-bit serial data words, allowing independent gain control for each channel without additional hardware.
Are there alternative parts compatible with the PGA2311U?
Compatible alternatives include the PGA2310 (through-hole DIP package) and the PGA4311 (4-channel version) from Texas Instruments. Third-party equivalents may also exist, but verify pinout, gain range, and supply voltage compatibility before substitution.
