  1. Interfaces Supply Texas Instruments COP888xG/CS LMC7211 LMV7239 LP2952 LP3990
    At times, designers face a limited amount of wire and/or a limited cost to communicate with a remote device such as a sensor. Many devices allow communication over an ac or dc power line employing an AM or FM modulation scheme. However, they tend ...

  5. 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 ...

  6. Supply Maxim MAX4210
    How do you deliver constant power when the load impedance isn't constant? That problem arises, for example, in trying to maintain a warm LCD display on an outdoor gas pump in cold climates. As the heating element changes temperature, its ...
