High-precision digital multimeters have many functions, are highly accurate and easy to automate systems, and can easily replace zero detectors, etc. However, their DC input amplifiers do not have the specific design required to fully match the characteristics of zero detectors. High-precision digital multimeters are deficient in some key respects. One of the key issues is the instrument's input bias current. The latest Fluke high-precision digital multimeter 8588A has a significantly smaller bias current, with a maximum of only 20pA. The bias current can also be adjusted almost to 0pA. And as time changes, the bias current changes very little, ensuring that the Fluke 8588A high-precision digital multimeter is a suitable product to replace the analog zero detector.
The circuit is very simple, with PMOS for the high end and NMOS for the low end, which are complementary. When one is turned on, the other is turned off.As shown in the figure above, it seems that the
More than a month ago, I started to use the STM8L151 + SI4432 wireless module to do a temperature acquisition experiment, powered by a 3.3v battery. After the basic functions were completed, the stand
