  1. Circuits Measurement Maxim MAX6674 MAX6675
    The thermocouple is a popular sensor for industrial temperature measurement because it's accurate, cost-effective, widely available, and suitable for a wide range of temperatures. It consists of two wires of different metal or metal alloys, ...

  3. Circuits Measurement Texas Instruments CD4066B SN74LVC2G74 SN74LVC3G14 OPA333 TLV431
    This Design Idea presents a low power short circuit finder that capitalizes on the ear’s sensitivity to changes in frequency. The heart of the circuit is a voltage-to-frequency converter (based on Ref. 1, Figure 13), which converts ...
