What does uPC7800A Series has "10 Hz ≤ f ≤ 100 kHz indicates?

Latest Updated:12/01/2006


Output Noise Voltage (Vn) Conditions column in Electrical Characteristics for the uPC7800A Series has "10 Hz ≤ f ≤ 100 kHz", but what does this indicate?

[Output Noise Voltage] uPC7805A

Parameter Symbol Condition MIN. TYP. MAX. Unit
Output noise voltage Vn TJ=25°C,10 Hz ≤ f ≤ 100 kHz   40 200 µVrms


The output noise voltage is measured under the condition of setting a bandpass filter to the output pin and the measured result is expressed as the effective (root mean square) voltage value. "10 Hz ≤ f ≤ 100 kHz" indicates the bandwidth of this bandpass filter. The unit is usually µVrms.
