MSPM0G1507: Replace the TLV9001 with an amplifier with a built-in MSPM0G1507.

Hi, 

Please refer to G1507's datasheet: 7.19 OPA 7.19.1 Electrical Characteristics

Load current is 9/30 mA.

Q1:Is it possible to cover the TLV9001 with an OPA or GPAMP built into the MSPM0G1507?

It's possible, MSPM0's internal OPA is better that TLV for most spec, but TLV's power supply is 5V and MSPM0 is 3.6V max.

For other spec, please check with customer whether [7.19 OPA 7.19.1 Electrical Characteristics] these spec can cover the customer's requirement.

Hi Helic,

 I apologize for the late reply.

I spoke with the customer and cleared up a misunderstanding about how to use it.

When used as shown in the diagram below, is it correct that OPAx_OUT can output 9/30mA?
The voltage range is 3.3V and there is no problem.
"OPAx_OUT" is connected to a driver IC, which requires a certain voltage/current(3.3V/Max 10mA).

Hi Helic,

Thank you for your reply. I understood.

Hi,

Sorry for additional question.

Is it correct to that sink=Max-30mA, source=Max+30mA?

Best regards,
O.H

Thank you your quick support!
