EDN A true-differential, power-source-free, high-input-impedance amplifier with bipolar output would present distinct advantages in remote devices. Such an amplifier, with its bipolar output, would be a better choice than a unipolar, 4- to 20-mA ...
EDN If you use an ADC to monitor a system's power-supply voltage, you may encounter situations in which the supply voltage exceeds the ADC's reference voltage (Figure 1). However, the ADC's input voltage cannot exceed its reference ...
Will Hadden, Maxim Integrated Products EDN A small and simple circuit derives 5 V from the 48 V rail that telecomm applications typically use (Figure 1). Useful for gate bias and other purposes, the 5 V supply delivers as much as 5-mA output ...
Alfredo Saab EDN Temperature sensors must sometimes operate at locations whose return potentials differ considerably from that of the data-acquisition system's common that is, equipotential ground. In consequence, the temperature sensor's ...
Minh-Tam Nguyen, Maxim Integrated EDN Unlike the four-wire SPI, QSPI, and Microwire data-interface standards, I 2 C and SBBus buses require only two wires for data transmission, because they send and receive over the same wire. The circuit in ...
John Guy, Maxim Integrated Products EDN Advances in semiconductor technology have allowed ICs to replace many mechanical relays, but relays still dominate in high-current circuits that must stand off high voltages of arbitrary polarity. Contact ...
Reinhardt Wagner, Maxim Integrated Products EDN This Design Idea describes a simple alternative to a nonvolatile gating function you typically implement using PAL (programmable-array logic), GAL (gate-array logic), or a CPLD ...
John Guy, Maxim Integrated EDN The increasing acceptance of Class D amplifiers has helped them gain market share from their linear Class AB brethren. That acceptance is no surprise; the advantages of Class D amplifiers are legion, but such ...
Jim Christensen EDN As higher levels of power dissipation underscore the need for cooling, more and more fans are finding their way into small electronic enclosures. The dust that fans pull into these enclosures can, however, cause major problems ...
Neda Shahi EDN Recent advances in operating efficiency have expanded the use of LEDs from one of mere indicators to becoming driving forces in electronic lighting. Increased reliability and ruggedness (versus other lighting technologies) gives the ...
