Onchip opamps for STM32MCU

Overview

---

DAC3 and DAC4 of STM32G4 MCU do not have internal buffer at output, therefore onchip OPAMP must be configured as follower to drive output.

Onchip OPAMP peripherals on STM32MCU can be used as

• Onchip ADC PGA
• Onchip DAC Driver
• Standalone TIA circuit
• etc.
