Linear Technology has produced a high-power dual voltage reference, allowing the reference replace the circuit power supply regulator. Specs are excellent, with outputs offering 0.05% initial accuracy, 10ppm/°C temperature drift and 1.5ppm p-p of noise from 0.1 to 10Hz. With no capacitor on the noise reduction (NR) pin, voltage noise density is around 150nV/rt(Hz) until ...
