LMX2595: Absolute rating of Vin input

Taketo Sato

Part Number: LMX2595
Other Parts Discussed in Thread: LMX2592,

Hello team,

I have a quick question.

LMX2595 datasheet doesn't mention absolute max rating of Vin(Input voltage to pins other than VCC pins). LMX2592 has the information. Can I think LMX2595 also has same absolute maximum rating as LMX2592?

Hello Taketo-san,

Yes, please ensure the OSCin input stays under Vcc+0.3 V.

Thanks,

Hello Vibhu-san,

Thank you for your comment. Let me confirm again.

LMX2592 datasheet states following as absolute max rating.

VIN (Input voltage to pins other than VCC pins): min -0.3V, max Vcc+0.3V;
VOSCin (Voltage on OSCin): <=1.8Vpp with Vcc applied, or <=1Vpp with Vcc=0;

You answered "Yes, please ensure the OSCin input stays under Vcc+0.3 V.".

Does this mean LMX2595 VIN absolute range is same as LMX2592, but VOSCin absolute range of LMX2595 is different from LMX2592 and must be under Vcc+0.3V?

Hello Taketo-san,

Yes, please stick to Vcc + 0.3 V for all input pins including OSCin.

Thanks,

Hello Vibhu-san,

I understand. Thank you.

Could you consider to add this to LMX2595 datasheet when next revision is happened?

Hello Taketo-san,

I've made a note of this. I will check to see if this is possible to add into the next revision.

Thanks,
