A simple circuit can improve the dynamic performance of a phototransistor for use in low- to medium-speed applications as fast as 100 kbps, such as optical isolation of an RS-232C serial line...

Meters that indicate analog levels via a moving-pointer meter, a numeric display, or a column of LEDs typically occupy considerable panel area and require more than a casual glance to read...

Applications for using a single pushbutton to advance a circuit to its next logical state are legion. Typically, there are just “on” and “off” states, but there can be more...

There have been numerous circuits published in EDN as design ideas for the past few months, centering around the “Flip ON Flop OFF” circuit originally published by Stephen Woodward. These are all designed for DC voltages less than 15 V...

This scheme makes power-capable DACs with double-digit wattage outputs...

Ampleon announces the release of a new high-efficiency GaN-based 2.4 GHz RF power amplifier lineup, designed for industrial, scientific, medical applications...

This article will illustrate how special converters equipped with PassThru mode can be useful when the circuit’s input voltage is too high or too low to power a load...

There is a new product type in the industry, the digital low dropout linear regulator. It offers telemetry and adjustability of a linear power supply in a very small footprint...

Asahi Kasei Microdevices Corporation has released to production the AK4497S, an enhanced premium D/A converter featuring our most refined low-noise technology, and the AK4498EX, the latest addition to our series of two-chip DAC solutions...

Thanks to its internal hysteresis, the highly useful Schmitt-trigger circuit accepts a low-slew-rate input signal and produces a clean, glitch-free output transition. Unfortunately, user-programmable logic devices, such as CPLDs and FPGAs, generally offer no direct method of synthesizing Schmitt-trigger gates and buffers...
