About the rated current of the output terminal of LTC2053

Hi Knj:  Minimum output currents are guaranteed by the "Output Voltage Swing" tests.  So, for example, on +/-5V supply we guarantee +/-4.5V output swing onto a 2k load, thereby guaranteeing +/-2.25mA capability (that's over Temperature).

For higher currents, you can consult the typical "Output Voltage Swing versus Output Current" plots further down in the data sheet.  You can see the output stage is starting to faint much north of 10mA.

I notice there's no loaded Gain test.  However, I do know that the internal opamp is practically identical to LTC2050 which guarantees Gain with a 10k load.  So to maintain the uV kind of accuracies, you wouldn't want to load the LTC2053 heavier than 10k.

Hope this answers all your questions.

Glen.

Thank you for your reply.
I understand that if you want to maintain accuracy, you should consider what you have received.

Let me check only one additional point.
Is there a maximum rating that would cause the IC to break if the output current is more than mA?

I would be grateful if you could reply.

How is this situation?
I would appreciate it if you could tell me the rated output current that would break the IC.
