High-Speed Op Amp Enables Infrared (IR) Proximity Sensing
By wordpainter Nov 14th, 2009
|
This sensor is basically a simple IR transceiver that generates IR modulated signal at 10kHz, then amplifies the reflected signal with a single op amp (MAX4230), which is also configured as a 2nd-order bandpass filter to demodulate the 10kHz IR signal. |

Speed Up Caculation with eMAC and MAC in ColdFire
By allankliu Nov 12th, 2009
|
ColdFire integrated enhanced multiply accumulate (eMAC) unit as a fundamental function block. Many algorithms of DSP processing and cryptography heavily rely on add and multiply operations, which can be boosted with MAC and eMAC. |

Set Your Holiday Lights to Music
By wordpainter Nov 8th, 2009
|
This circuit which allows you to set your holiday lights to music does so by digitizing music with a 12-bit A/D converter, monitoring the resulting digital outputs, and producing a logarithmic thermometer-code format to control multiple power outlets. |

Smart Cable Aids Quality Control and Authentication
By wordpainter Nov 7th, 2009
|
Cable authentication problem are very common. Embedding a DS2431 (1-Wire) chip in the near end of a cable allows a system processor to identify a cable (manufacturing date, revision, configuration, calibration data, etc.) and to authenticate it (to prevent the use of inferior counterfeits). |
