MIKROE-6818

MIKROE-6818 is a Volume 3 Click compact add-on board for digitally controlled analogue volume adjustment for professional and high-end consumer audio systems. It is based on the PGA2311, a high-performance stereo digital volume control IC, widely used in applications that require low distortion and fine gain resolution. The board features two independent audio channels controlled via a 16-bit serial interface, allowing separate left and right channel gain settings with 0.5dB step resolution across a wide range from +31.5dB gain to −95.5dB attenuation. Volume 3 Click includes locally generated low-noise symmetrical ±5V analogue supply rails, hardware and software mute support, zero-crossing detection to minimize audible artifacts, and SPI communication interface. This Click board™ is well suited for audio mixers, preamplifiers, home audio equipment, professional sound systems, and digitally controlled analogue audio interfaces. It is fully compatible with the mikroBUS™ socket.
