DA9062 Riref accuracy

Hi,

the datasheet specifies a Riref of 200k+/-1%. The output voltages accuracy is specified with +/-3%.

I am wondering if the output voltages accuracy could be improved to +/-2.1% by using an Riref with a tolerance of +/-0.1% instead?

Regards,

Thomas

Hello Thomas,

Increasing the accuracy of the IREF resistor, should improve the output voltage accuracy.
