Search results: 2,397 Output: 31-40 Stephan Goldstein, Analog Devices EDN The human eye's highly nonlinear response to light levels poses problems for designers of adjustable lighting. Simple hardware or software linear-control methods compress most of the apparent intensity ... 27-02-2018 Ken Whiteleather Electronic Design Current-mode control loops (particularly the popular 4- to 20-mA controls) are used in many industrial applications because of their immunity to induced EMI from motors, contactors, relays, and other sources. ... 27-02-2018 Dan Meeks EDN Most current microprocessors, DSPs, and field-programmable gate arrays integrate hardware and software resources that support either or both of two common interface standards SPI (serial-peripheral interface) and I 2 C ... 22-02-2018 Stephen Woodward EDN An earlier Design Idea illustrated one approach to that traditional headache for the analog designer: the dreaded ground loop ( Reference 1 ). That Design Idea described a simple and efficient multichannel circuit. But ... 22-02-2018 Clayton Grantham EDN Many process-control sensors, such as thermistors and strain-gauge bridges, require accurate bias currents. By adding a single current-setting resistor, R 1 , you can configure voltage-reference circuit IC 1 to produce a ... 15-02-2018 Jim Drew, Linear Technology Design Note 487 Introduction Redundant arrays of independent disks, or RAID, systems, by nature are designed to preserve data in the face of adverse circumstances. One example is power failure, thereby threatening data ... 15-02-2018 Marián Štofka EDN Analog Devices’ digitally gain-programmable AD8231 instrumentation amplifier exhibits zero offset. It has programmable voltage gains, which are successive powers of two, from 2 0 = 1 to 2 7 = 128. The AD825x ... 08-02-2018 Jim Williams, Linear Technology EDN If you need to produce extremely fast pulses in response to an input and trigger, such as for sampling applications, the predictably programmable short-time-interval generator has broad uses. The circuit of ... 08-02-2018 Jim Williams EDN Impulse-response and rise-time testing often require a fast-rise-time source with a high degree of pulse purity. These parameters are difficult to achieve simultaneously, particularly at subnanosecond speeds. The circuit in Figure ... 08-02-2018 Bob Marshall EDN In new mixed-voltage systems, it is often necessary to level-shift a control signal from a high level to a low level. An open-drain device, such as the 74LVC2G07 , easily performs this shift. However, when a bidirectional signal ... 08-02-2018
