    Power Good(OK) Circuit References?

    All pg circuits ive crossed by are based on 2 comparators. if the need for a 1.8v dc surveillance is due a specific ic demand , maybe a voltage supervisor ic would worth some checking. good luck.

    [SOLVED] Design of Eight-channel Temperature

    The previous sugestion on 1wire interface is the best call. after implement the base code u can deploy from 1 to 64 sensors in the same bus - factory ditigal calibrated sensors with up to 12 bit resolution. Also the ds18b20 has internal eeprom, so a smart code can use that extra bytes to save...

    What Are Input and Output impedances in simple words?

    Been working lately on opamp's cause of a PIR sensor, and learned that a voltage follower/unity gain stage is a good circuit if u want somehow connect diferente impendance circuits. But i think that the 20k load resistor sugested before is a good starting point. Nothing better than the usual...
