We have developed a 0.8µVRMS (10Hz to 100kHz) low noise power supply reference board that is ideal for audio equipment, CCDs and minute signal sensor processing circuits.

For audio equipment, a low noise power supply is required to improve sound quality. In addition, low-noise plus/minus power supplies are required for analog circuits in CCD and minute signal sensor processing circuits.

This reference board uses two analog devices linear regulators. I am using LT3045 as positive linear regulator and LT3094 as negative linear regulator. Both the LT3045 and LT3094 are low noise products of 0.8uVRMS (10Hz to 100kHz) and ultra-high PSRR, making them ideal reference boards for precision analog circuits.
