How does the resistor connected to the input pin of the NJU7890 affect the attenuation factor accuracy?
How does the resistor connected to the input pin of the NJU7890 affect the attenuation factor accuracy?
The input resistor built into this product can obtain a relative value (ATT±0.7%) depending on the wafer process, but the absolute value may vary by ±15%.
The effects of "external resistors" and "±15% on-board resistance variation" on accuracy are described below.
