Sensor circuit

The LM358 consists of two independent, high-gain operational amplifiers in a single package. An important feature of this integrated circuit (IC) is that it does not require separate power supplies for the operation of each comparator, accommodating a wide range of power supply voltages. The LM358 can be utilized as a transducer amplifier, DC gain block, and more.

The LM358 operational amplifier is designed for versatility in various applications, making it a popular choice in electronic circuit design. Each of the two amplifiers within the package can operate from a single power supply voltage, typically ranging from +3V to +32V for a single supply or ±1.5V to ±16V for dual supplies. This flexibility allows for integration into a variety of systems without the need for complex power supply arrangements.

In terms of performance, the LM358 features a high open-loop gain of approximately 100 dB, with a bandwidth of around 1 MHz. The input common-mode voltage range extends from the negative supply rail to about 1.5V below the positive supply, enabling it to handle a wide range of input signals. Additionally, the output stage is designed to drive loads directly, providing a low output impedance, which is essential for buffering applications.

The LM358 is frequently employed in signal conditioning applications, where it amplifies low-level signals from sensors or transducers. Its ability to function as a differential amplifier makes it suitable for applications requiring precise measurement and amplification of small voltage differences. Furthermore, it can be configured as an inverting or non-inverting amplifier, depending on the desired gain characteristics.

In practical applications, the LM358 can be found in various devices, such as audio processing equipment, industrial automation systems, and instrumentation devices. Its robust design and ease of use contribute to its widespread adoption in both consumer and industrial electronics. Overall, the LM358 operational amplifier is a reliable and efficient component for engineers seeking to design high-performance analog circuits.LM358 consist of two independent, high gain operational amplifier in one package.
