  1. Lawrence Mayes EDN In audio-mixing applications, one frequently required function involves mixing a monaural or single-channel source into a stereo-sound field. Audio engineers refer to a panoramic-potentiometer circuit as a circuit that generates ...

  2. Catherine Chang, Philip Karantzalis and Aaron Schultz, Linear Technology Design Note 564 Our op amp family has expanded with industry-leading speed versus supply current. The LTC6258/LTC6259/LTC6260 family (single, dual, quad) provides 1.3 MHz ...

  3. Dennis Eichenberg EDN The circuit in Figure 1 provides a simple, nonvolatile means of monitoring critical ac-power failures. Monitoring the power is important in such systems as heating and refrigeration, in which damage can occur if the ac power ...

  4. 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 ...

  1. Horst Koelzow EDN The basis for this Design Idea is a classic two-transistor current source (Figure 1). Current through R 1 depends only on the V BE (base-emitter voltage) of Q 2 and on the value of R 1 itself. The V BE of Q 1 has no impact on the ...

  2. Alfredo del Rio EDN Many flash ADCs, such as Texas Instruments' ADC1175 , have a recommended operating input-voltage range of 0.6 to 2.6 V. However, in some applications, you must convert a symmetrical analog-input signal. The circuit in this ...

  3. Bob Bell EDN Designers of dc/dc switching power converters face the challenge of controlling EMI (electromagnetic-interference) emissions produced during normal operation. If large enough, these emissions conduct through power lines or radiate to ...

  4. Stephen Woodward EDN Inexpensive, 16-bit, monolithic DACs can serve almost all applications. However, some applications require unconventional approaches. This Design Idea design concerns circuitry I recently designed for a tunable-diode laser ...

  5. Henry Santana Electronic Design Europe The general approach to an electronic load is to use a transistor across the input terminals so the current flows from drain (collector) to source (emitter). A resistance is effected by causing a current flow ...

  6. Greg Sutterlin EDN The simplicity of low-side current monitoring can mask the advantages of a high-side approach. You can monitor load currents in a power supply, a motor driver, or another power circuit on either the high or the low side (ground). ...
