Abstract: The circuit in the figure below includes a 10-bit digital-to-analog converter (DAC) with 3-wire serial input that operates and maintains a visible-light laser diode at constant average optical output power. A separate digital inp...

摘要：MAX4007是一款高精度、高邊、高壓電流監(jiān)測器，設計用于監(jiān)測光纖系統(tǒng)光電二極管的電流。該應用筆記描述了一種在GPON突發(fā)模式工作中提高MAX4007響應時間的簡易方法。 ...

Abstract: Two integrated circuits (ICs) and some associated components form a voltage-controlled sawtooth generator that costs less than $3 and produces an auxiliary square wave at the same frequency. The generator is useful in a varie...

Abstract: With a few op amps and some external components, you can build a pulse generator with variable frequency and duty cycle. The natural choice for generating a pulse of variable frequency and duty cycle is a good b...

Portable systems often use LEDs of different colors-white for the display backlight, green for keypad illumination, red for power, etc., and in varying quantities of each. Typically the LEDs are driven by at least two power supplies, one f...

Abstract: Circuit including a step-up switching converter steals power from a parallel port, providing 5V at 8mA with efficiency as high as 94%. The circuit of Figure 1 steals energy from a parallel port or from any limit...

摘要：為了降低對直流逆變器瞬間電流的需求，DS3984/DS3988冷陰極熒光燈控制器采用順序啟動突發(fā)亮度調節(jié)的方式，控制LCD顯示器的每個通道。 圖1給出了DS3984/DS3988冷陰...

摘要：DS3984和DS3988是多通道冷陰極熒光燈(CCFL)控制器。DS3984支持多達四通道，DS3988支持八通道。這些控制器使用推挽式驅動架構，可將DC電源電壓轉換成為驅動CCFL所需的高壓AC波形。...

Abstract: A simple RC filter with an external transistor driver rejects LDO noise. A plot of noise density vs. frequency shows that the filter rejects LDO noise by more than 46dB, and achieves a noise floor of 7nV/...

Abstract: This ultra-low-noise LDO combines low-noise components with filtering to achieve an output noise performance of 6nV/ at 1kHz. Of the many low-dropout (LDO)...
