Hello As I finished the next preamplifier I wanted to share the project on the forum Attachment: 20180716_141856(1).jpg Attachment: 20180716_141935(1).jpg The PGA2311 device is a high-performance, stereo audio volume control designed for professional and high-end consumer audio systems. The PGA2311 uses an internal high-performance operational amplifier to yield low noise and distortion. Device functions: - Volume adjustment -95.5dB to + 31.5dB with a step of 0.5dB - Volume control with remote control and encoder - Balance adjustment (remote control and encoder control) - Mute function (remote control) -ON / OFF (remote control and switch control) - Memorizing settings after switching off - Real time clock + date based on PCF8583 -Cooperation with popular 2x16 displays with HD44780 driver. - RC5 pilot (each Philips) - Input select (5 sources) The program was written in Bascom, it takes 51% of the memory Fuse bits set on internal 8Mhz dnt forgot turnoff JTAG ps. I am asking for opinions what you think about such a device |
