Anthony Smith EDN Requiring no rectifier diodes, the positive peak-detector circuits in figures 1 and 4 exploit the open-drain output of a Texas Instruments TLC372 fast comparator, IC 1 . Both versions of the detector are simple and inexpensive and ...

Guy Hoover, Analog Devices Electronic Design A high-resolution SAR ADC often needs a higher-order antialiasing filter, such as the third-order version provided by this low-noise, low-power design. For many analog-to-digital converter (ADC) ...

Mike Irwin EDN Professional-audio equipment commonly uses Analog Devices‘ high-performance, quad-voltage-controlled SSM2164 attenuator. The control response is 30 dB/V, with 0 V producing unity gain. Attenuation increases as the applied ...

Bill Schweber Electronic Design A family of PTC thermistors conquers the calibration and linearity errors associated with conventional NTC temperature devices. Temperature is the most widely measured physical variable and designers have many ...

Luca Bruno EDN A traditional method of driving a low- to medium-power permanent-magnet dc motor involves using four MOSFET or bipolar transistors in an H-bridge configuration. For example, in Figure 1, the motor connects between collector pairs C 1 ...

Tom Gay EDN In low-power, single-supply analog applications, it is often desirable to maintain precise control of voltages much greater than the positive-supply rail. The circuit in Figure 1 allows you to amplify the input voltage, V IN , by a ...

Marián Štofka EDN Two amplifiers produce voltages that you can use in a variety of applications. The circuit in Figure 1 generates two analog voltages, which you can vary in a complementary manner. When the straight output voltage ...

Paul Rako Electronic Design Using a bootstrapping scheme with a JFET can enhance a photodiode’s ac response, but adds unwanted dc voltage. Remedy that problem with a matched dual-JFET. Linear Technology has a good application note [1] about ...

Abhirup Lahiri Electronic Design Inductors designed with active elements are very desirable to designers today because conventional spiral inductors are too big, too heavy, and too costly, and they require tuning. During the last few decades, ...

Chau Tran and Paul Mullins, Analog Devices EDN You sometimes need to measure load currents as large as 5 A in the presence of a common-mode voltage as high as 500 V. To do so, you can use Analog Devices’ AD8212 high-voltage current-shunt ...
