LMX2594: Need DC Output Quiescent Current rating

Hi Gabriel,

I am afraid I do not understand the question, would you have the customer described a little bit more in detail what data they are looking for? Thank you.

Hi Noel,
The customer is looking to implement this device, they just want to know a quiescent current rating with respect to RFoutAP/AM and RFoutBP/BM, before they move forward. Many TI devices have this rating, but none in the LMX25xx family do not show it in their respective datasheets.

Thanks,
Gabriel

Noel, I am the customer in this case. My concern is the quiescent current on the output pins of the device that are pulled up to VCC via 50 Ohm resistors (R37-R40 in figure 50, sheet 56. Pull-up resistors indicate open-collector/drain outputs to me, and that means the 50 Ohm resistors are will carry some finite DC current. I need to know the actual current in order to determine if the 0402 resistors recommended on sheet 45 are sized properly for our application. That specification is not listed in the datasheet that I can find.

Hi David,

OK I understand the question. There is about 6mA current flowing through each resistor.
