But when 60Hz transformers are used in 50Hz territories, the 20% change down in frequency increases transformer losses. Tightly designed types may prove unsafe or unreliable in professional use, where the amplifier is working hard in a confined space; or too noisy in domestic use. The ...
The 2.5 V voltage reference used in this application is the ADR4525 from the ADR45xx series of plastic-packaged voltage references, and it provides high precision, low power, low noise, and features ±0.01% (±100 ppm) initial accuracy, excellent temperature stability, and low output noise. ...
