FAQ on pull-up/pull-down resistors: part 2
Even this relatively simple circuit arrangement has subtleties that affect performance. Part 1 explored the role of pull-up and pull-down resistors to ensure that the binary (digital) circuit points are at an unambiguous 1 or 0 level. This part explores basic issues of sourcing, sinking current, and resistor sizing. Sourcing and sinking current Q: What […]
FAQ on pull-up/pull-down resistors: part 1
Even this relatively simple circuit arrangement has subtleties that affect performance. In the crisp, clean, theoretical binary world, signals exist in only two unambiguous states, generally called 1 and 0 (one and zero). However, when engineering students, hobbyists, and digital-only professionals get into the hands-on real world of circuits and systems, they find that binary […]
0201-size, automotive-grade resistors bring enhanced reliability in consumer and industrial applications
Many types of electronic devices now benefit from the higher reliability of automotive grade resistors. By specifying automotive grade resistors, design engineers in any market segment can increase electrical stability and environmental reliability without the significant increase in cost normally associated with established reliability resistors. Stackpole’s RMCA series is AEC Q200 qualified and provides excellent long-term reliability. The […]
The why and how of matched resistors: part 2
Paired resistors with low-temperature drift are critical to many precision analog circuits. The previous part discussed the need and “why” for matched resistors, as well as errors due to tolerance and TCR. This section transitions to their physical embodiment and looks at the “how” of obtaining needed matched resistors to minimize errors, temperature-related effects, and […]
The why and how of matched resistors: part 1
Paired resistors with low-temperature drift are critical to many precision analog circuits. Achieving high performance, precision, and consistency in an analog signal chain requires attention to subtle details. In many cases, these details include the absolute accuracy of passive components such as resistors and the more subtle effects on component characteristics due to aging, mechanical […]
