Ultra-Low Noise, Ultra-High PSRR +/-12V DC/DC with LT3045

+/-12V Power Supply Reference Board for High-Precision, Ultra-Low Noise Analog Circuits

The Mpression Ultra-Low Noise, Ultra-High PSRR +/-12V DC/DC Board with LT3045 is a low-noise (0.8µVRMS at 10Hz to 100kHz) reference board for audio equipment and small-signal sensor systems.

Audio equipment designs require low noise power supply to improve audio quality, and small-signal sensor processing circuits like in CCD sensors require low-noise positive and negative power supplies for analog circuitry.

This reference board is designed using two Analog Devices linear regulators: LT3045 for the positive side linear regulator, and LT3094 for the negative side linear regulator - both with ultra-low noise (0.8µVRMS at 10Hz to 100kHz) and ultra-high PSRR, perfect for high-precision analog circuits.
