Hi:

I want use PGA900 UART with RS485 transceiver as RS485 output for loadcell.

But I am worry about communication stability of PGA900 UART.

Because PGA900 can not have external crystal, how about the stability of PGA900 UART baud rate?

Is the internal crystal of PGA900 very stable  and accurate?

Our loadcell will be used in from -20 degree to 60 degree.

thanks
