High voltage differential probe

Overview

For discussion, please enter the Q group: 631060292. The original picture was drawn with eagle. Please check whether there are any conversion errors when making the board. TYPEC charging, battery protection, can also be used without batteries. Gain 500X measurement range 1200V30Mhz There are no overload detection, gear adjustment and other advanced functions. The negative 2.5V regulated voltage will not be stable when the battery level is lower than 30%. (Negative-voltage LDOs are too expensive, so try to use them with full power.) The current version has a large wiring parasitic capacitance and a relatively low bandwidth. It will be upgraded later to
install domestic gs8091 and other op amps and can also be used. The main picture is a direct measurement of 220V AC
