tm7780 sop-8
tm7780 is a single-phase metering chip, whose output cf is used to calculate electric energy, and cfa is used to indicate the effective value of current or voltage. tm7780 uses a new algorithm internally. when the power value of the input signal is greater than the internal noise value, the metering module starts to measure correctly. this product has excellent performance and reliable quality.
5v power supply, work current typical value less than 3ma
the oscillator frequency is about 3.579mhz, and the power supply voltage suppression ratio is less than 0.01/v.
by configuring the set pin, the effective value of the output current or voltage of the cfa reaches an accuracy of ± 0.5%.
encapsulation form: sop8
single-phase multi-function watt-hour meter, smart socket, charging pile, digital signal display instrument, street lamp, small household appliances and other occasions where voltage, current and power need to be measured.
