Power measuring & nbsp; U7-1 & nbsp;. Amplifies weak signals DC and AC voltage in the frequency range 0-100 kHz

Due to application of the differential switching circuits of the input stage and thermostatting chips of this cascade are achieved high accuracy amplification , small zero drift, good suppression of common mode and common mode

Having filter low and high frequency allows the device to U7-1 to limit the frequency response in order to reduce noise
