 Hello and welcome to this presentation of the STM32U5 embedded operational amplifier. It covers the features of this IP which is widely used for conditioning analog signals. The STM32U5 integrates two op-amp modules which are very similar to the STM32L5. These are general purpose analog amplifiers which reduce the need of an external standalone op-amp. As these op-amps can be configured in standalone mode with all terminals available for the user, it's possible to use them as a voltage follower, non-inverting and inverting amplifiers, as well as analog filters such as low or high pass filters. They can also act as a pre-amplifier for the ADC input. The table shows performance parameters for the STM32U5s and STM32L5s op-amps. Compared to the STM32L5, the analog supply voltage range of the STM32U5 is extended from 1.6 to 3.6V. The gain bandwidth is also extended to 2 MHz in normal mode and 0.5 MHz in low power mode. Note that the op-amp module present in the STM32U5 supports a high speed mode that is activated by setting a control bit. The slow rate characteristics are improved in the STM32U5's op-amp module. By using an internal feedback resistor, the op-amp can also be used as a programmable gain amplifier or PGA. When enabled, it can be in calibration mode, all input and output of the op-amp are then disconnected or in functional mode. To facilitate PCB design, a SPICE simulation module will be provided upon demand. This table shows the internal and external connections of the op-amp inputs and outputs. Each op-amp module has two inputs, inverting and non-inverting, and one output. The non-inverting inputs can be connected to either a GPIO pad or internally to a DAC output. The inverting input is used for feedback when PGA mode is selected or can be connected to a GPIO pad. The output is either connected to a GPIO pad or to an ADC input. By connecting the op-amp to its dedicated inputs, it can be used as a transimpedance amplifier. A transimpedance amplifier is a current to voltage converter. In addition to this presentation, you can refer to the following presentations for the peripherals connected to the STM32U5's operational amplifiers. Analog to Digital Converter or ADC and Digital to Analog Converter or DAC, General Purpose Input Output or GPIO.
