Hi,
I'm currently designing a product that I want to work in both Europe and in the US (just by swapping a few components, TD1508 device and antenna matching circuit).
I'm swapping between using a battery at 3.6V (small voltage drop across diode gives 3.5V, keeping under maximum rating) and an external switching power supply.
I assume it's alright to use 3.5V input instead of the standard 3.0V or 3.3V?
I just want to confirm that using the recommended circuit in the TD1508 datasheet (Section 11.1) will be alright for the TD1208R as well??
The TD1208R only mentions using a bead.
Thanks in advance
