LM6132: what is the absolute maximum rating of V- pin

Part Number: LM6132

Dear team,

We can see V+'s range in the datasheet, but I don't know the range of V-. Could you please tell me the range of V-?

My customer's condition is V+=9V, V-=-9V, is it ok?

Thanks & Best Regards,

Sherry

From the point of view of the device itself, all voltages are measured relative to V−. So V− always is 0 V.

In the customer's circuit, V− = 0 V, V+ = 18 V, which is OK.

Hi Ladisch,

My customer use V+=9V, V-=-9V in the old project, but our device is not damaged. Because our datasheet doesn't specify V-'s range, my customer still want to confirm with us.

Thanks & Best Regards,

Sherry

V+ is measured relative to V−. So you can read the entry in the table as 1.8 V ≤ (V+ − V−) ≤ 24 V.

V+ − V− is 18 V, which is OK.

Hi Sherry,

that a bipolar supply voltage is allowed with the LM6132 can also be seen from the many figures in the datasheet :-)
