Can G491 OPAMP6 be connected to ADC3?

In RM0440, STM32G491 is Category 4.Therefore OPAMP6 can be connected to ADC3 refer to RM0440 21.4.4(ADC Connectivity)But I cannot find check option for OPAMP6 in ADC3 setting.Is it unavailable? or not implemented yet?

Is it possible to use the internal OPAMP from the STM32G4 series with only the VINPx pin assigned to a physical pin? Configured as non-inverting, negative feedback with a gain.

I would like to implement a current sensing using a grounded shunt resistor. Therefore I would like to use the build-in OPAMP from the STM32G491 Series. But I'm not satisfied with the CubeMX configuration.In AN5306 I found a configuration under 4.4.1...

STM32G431 non-inverting opamp with internal connection to ADC without VINM0 ext IO

Hello, I want to connect the op-amp built into the microcontroller directly to the ADC input in a non-inverting mode, without outputting the negative input (VINM0) outside, but I cannot find this configuration in CubeIDE.For some reason, in the mode ...

Resolved! STM32G474 Opamp: CubeMX always enables negative in "PGA Internally Connected" mode

With the G4 Cube package version 1.1.0 I could configure OPAMPs as "PGA Internally Connected" and only the positive Input is enabled. With version 1.3.0 also the negative input is enabled. OPAMPs where this is not possible due to pin conflicts are s...

STM32CubeMX 5.6.1 STM32G4 OPAMP/ PGA configuration issue?

Hello,Fully new with OPAMP, configuration, I made some tries, and for me ther is an issue on the CubeMX code generator. If I want use an OPAMP with PGA with positive gain, I only need non inverting input and output. There is no way to specify this co...

OPAMP's of STM32G474 reserve not needed output pin when using internal output connection ? (probably BUG or incorrect CubeMX behavior/ no correct option).

Hello ST community,When I use OpAmp's of STM32G474 and configure all of them to internal ADC connection, all of them still reserve external output pins as analog .I'm using : OpAmp's in Inverting mode, with PGA enabled, positive input internal conne...

Hello, for a STM32F474RBT device, STM32CubeMX V.5.4.0 with Firmware V.1.1.0 allows to put OPAMP1_INP and COMP1_INP on a single port PA1. Is this really a valid configuration, or is it a CubeMX bug?

I have to use OPAMP2. I have to wires. I want to get the difference between these two and amplifiy the signal with a adjustable faktor. Can someone tell me in which mode i have to use the OPAMP and how to configurate in MXCUBE?

STM32 NUCLEO-L476RG OPAMP Output not below 1.4 V

Posted on March 26, 2018 at 17:00Hey guys,i am right now working on the Nucleo L476 RG Board. I generated source code with STM32CubeMX (v4.25). I am using the internal opamp in 'Follower' mode and reading the output with the on-board adc. VCC is 3.3...
