Looking for a clean power supply for a sensitive analog circuit? Analog Devices describes the sources of noise in LDO voltage regulators, and provides some examples to limit and combat the noise. In general, LDO noise comprises two components: intrinsic, or internally generated noise, and extrinsic, or externally generated noise. Thermal and 1/f noise are […]

App note: Thermocouples, and design guidelines for AD59X TC amplifiers
Analog Devices has an app note on thermocouple basics, and some guidelines on how to design projects with their AD595 and AD594 thermocouple amplifiers. Temperature is the most frequently measured physical parameter. However, the techniques of temperature measurement are grossly misunderstood, often resulting in serious inaccuracies or meaningless data. Thermocouples are basically two wires made […]
