Bonnie Baker, senior applications engineer at Texas Instruments and regular EDN columnist, demonstrates a simple way to add DAC functionality to a microcontroller-based system using only an op amp and ...

Proper calibration of test instruments is crucial for meeting the stringent performance requirements of many equipment types. Calibration results must frequently meet national and international ...

An analog- or a mixed-signal lab cannot have too many voltage sources. A simple, reasonably high-precision voltage source can set bias points in an op-amp circuit, tweak the feedback node of a power ...

When you measure a voltage, how do you know that your measurement is correct? Because your multimeter says so, of course! But how can you trust your multimeter to give the right reading? Calibration ...

Proper calibration of this test equipment is crucial to meeting the strict performance requirements of many high-voltage systems. Calibration results often need to comply with national or ...

As children, we all probably had our ideal career paths. As an adult do you still harbor a secret desire to be an astronaut, or to drive a railroad train? Or have holders of other jobs become the ...

VOLTAGE REFERENCES generate wideband noise spectrums. For most semiconductor devices, this spectrum usually has a wideband “white noise” component with relatively constant power density versus ...

UltraVolt, Inc., announced expansion of its popular line of precision high-voltage amplifiers - the HVA Series - capable of operating in DC, reversible, and amplifier modes. The new line of precision ...
