ChengQun launched voltage tester IC HT70xxA-2 series, is using CMOS technology of three feet a manufacturing voltage tester. This series of voltage tester offer 8 kinds of voltage test specifications choice, outside its representatives make up xx detecting voltage specification, range from 2.2 V to 8.2 V, each specification can meet the plus or minus 1% testing voltage accuracy, it can be used in various applications, such as the white goods, portable products, video conversion box, and medical treatment, measurement and safety system.
 

  HT70xxA-2 voltage tester series design, high precision of low power consumption by standard voltage source, comparator, lag circuit and output of drive. Using CMOS technology manufacturing, thus ensuring a low power consumption, to meet the most dc power supply, the input voltage can achieve 24 V range, add built-in lag circuit design and low temperature coefficient characteristics, to ensure the stability of the test voltage output, so more able to meet all kinds of application status of demand.

  This series of chip operating temperature for 40 ℃ ~ +-85 ℃, the encapsulation provide a TO92, SOT23-5 and SOT89 three, to meet customers of different application and design requirements.
