MSPM0L1306-Q1: Is it possible to mux two OPA inputs to one OPA

Intellectual 1445 points

Part Number: MSPM0L1306-Q1

Hi TI Team,

Is it possible to mux two OPA inputs to one OPA?

In the TRM of M0L1306 is shown that there are two signals which can me muxed before going in the OPA.

The datasheet doesnt show a IN1+ and IN0- & IN1- are sharing one pin.

Is there an option to use an OPA for two input signals?

Thank You!

Hi FM,

Here is the OPA0,1 pin connections from the datasheet. Are you asking if more than one channel can be selected at the same time on either the PSEL or MSEL muxes?

Hi Dennis,

Sorry I was focusing on the TRM where another OPA configuration is drawn.

I see now that I can no use 4 OPA inputs like for the G devices,

OPA0_IN0+

OPA0_IN1+

OPA1_IN0+

OPA1_IN1+
