Supply Voltage range for LMX2592EVM

Other Parts Discussed in Thread: LMX2592EVM, LMX2592

Hi,

In datasheet, it's mentioned that supply voltage for LMX2592EVM should be 3.3V. As it's difficult to get a precise 3.3V battery, can we use a 3.7V supply. What's the acceptable supply range for LMX2592EVM. 

  • Babu,

    The LMX2592 supply voltage range is 3.15 to 3.45 V.   There are internal regulators in the device, so performance is not too sensitive with respect to supply, except the outputs, as they have a pull-up  to the supply.

    3.7 V exceeds the 3.45V supply, so this is too high.  Likely the device may work in the short term, but there could be concerns about long term reliability over time when the upper voltage limit is exceeded.  So I can not recommend 3.7 V operation.

    Regards,
