11. Circuits protect outputs against overvoltage
    Measurement Supply Texas Instruments OPA551
    In test-and-measurement applications, you must provide overvoltage protection for the output terminals of amplifiers, power supplies, and similar components. The conventional way to accomplish this task is to add series resistors with the output ...

12. The Shannon decoder: A (much) faster alternative to the PWM DAC
    Signal Processing, Filters Texas Instruments CD74HC4053
    Readers will recognize the famous name Claude Elwood Shannon, widely renowned as the “father of information theory” and originator of many discoveries and inventions. Among these is an elegant and pioneering (First published in 1948!) ...

13. Single Op Amp Achieves Double-Hysteresis-Transfer Characteristic
    Analogue Design Texas Instruments TL081 LM311
    In process-control applications requiring discontinuous controllers, the most elementary choice is a two-position-mode or on/off controller. A typical example of such a controller is a space heater. If the temperature drops below a setpoint, the ...

14. AC/DC power-supply startup considerations for PMDC motor loads
    Supply Texas Instruments TL331 UCC256402
    Permanent magnet DC (PMDC) motors offer smaller solution size and increased efficiency in applications such as portable vacuums and cordless electric power tools. When designing an isolated power supply for PMDC motors, there are several ...

15. Drive LDOs To 0-V Output With Single Supply
    Supply Texas Instruments LM350A LM431 LM385-1.2
    Many electronics circuits begin operation at voltages below 1.25 V. But popular adjustable regulators such as the LM317 , LM350 , and LM338 can provide output voltages only above 1.25 V, and the L200 minimum is higher at 2.85 V. Fixed-output ...

16. Balancing power sharing of paralleled boost converters in speakers
    Audio Supply Texas Instruments LM5155 LM8261 TPA3221
    Audio amplifiers for high-power portable speakers such as trolley speakers usually operate with lithium-ion batteries, and these batteries can vary from a single cell to a few cells in series. Designers generally use boost converters to produce the ...

17. Inverted MOSFET helps 555 oscillator ignore power supply and temp variations
    Oscillators Texas Instruments LMC555
    Since its invention over a half-century ago by Hanz Camenzind at Signetics, the familiar 555 analog timer (in league with its updated pin-compatible CMOS descendants) has become an iconic design element incorporated into useful standardized ...

18. Constant-Current Source Creates Slope-Compensation Ramp in SMPS
    Analogue Design Supply Texas Instruments UCC28C43P
    A switched-mode power supply (SMPS) employing peak current-mode control (PCMC) requires a ramp signal to slope-compensate the inner (current) control loop. Slope compensation stabilizes the current loop, which would otherwise exhibit subharmonic ...

19. Add One Resistor to Give Bipolar LM555 Oscillator a 50:50 Duty Cycle
    Oscillators Texas Instruments LM555
    More than a half-century old, the ubiquitous and mind-bogglingly useful 555 analog timer has become a perennial object for both kudus and criticism. Most of the former and some of the latter is justified, but sometimes a supposed shortcoming will ...

20. Adjust 555-Based Generator's Duty Cycle without Affecting Frequency
    Oscillators Texas Instruments LM555
    A free-running generator built on the standard configuration of the 555 timer can't provide a duty cycle of exactly 50%. That's a well-known fact. Fortunately, there are several ways to get around this problem. The best is to place an extra ...
