The composite amplifier based on ad8253 meets the design requirements

Although binary is mainly used in electronic technology, decimal number is widely used in human-computer interaction. Therefore, the design usually needs to use a gain programmable amplifier with a gain to the power of 10. At present, the ad8253 monolithic instrument amplifier of anolog devices is digitally programmable when the voltage gain is 1, 10, […]

Chopper technology based on noise gain can improve dc accuracy

One of the most important indicators of operational amplifier is its input offset voltage. This voltage can be ignored for many operational amplifiers, but the problem is that the offset voltage will change with temperature, flicker noise and long-term drift. Chopping and automatic zeroing techniques have been available for many years, which can reduce the […]

Using high gain operational amplifier to realize the design of measurement amplifier and improve performance index

Measurement amplifier, also known as instrument amplifier or data amplifier, is a high-precision amplifier that can be used to amplify weak difference signal. It has a wide range of applications in measurement control and other fields. Generally, the measurement amplifier is mostly realized by special integrated module. Although it has high performance index, it is […]
