An amplifier using INA103 to set gain with external resistors

Source: InternetPublisher:走马观花 Keywords: Amplifier Updated: 2024/09/12

INA103 uses external resistors to set the gain amplifier

As shown in the figure, an amplifier with external resistors setting gain is used. The external resistors RF and RG form an amplifier with external resistors setting gain, and the gain G = 1 2RF/RG. When RF>10kΩl, the noise will increase and the bandwidth will decrease.
