STMicroelectronics LM358ADT Dual Operational Amplifier

The LM358ADT from STMicroelectronics is a versatile and widely-utilized dual operational amplifier (op-amp) that is designed to offer a perfect balance of performance, power efficiency, and cost-effectiveness. This device is a part of the LMx58 series of op-amps and is characterized by its low-power consumption and high-gain attributes, making it an ideal choice for a multitude of electronic applications.

Enclosed in an SO-8 package, the LM358ADT operates over a wide range of power supply voltages, from 3V to 32V for single supply configurations, or ±1.5V to ±16V for split supplies. This flexibility allows it to be easily integrated into both simple and complex circuits. The op-amp features a typical low supply current of 0.7mA, which is particularly advantageous for battery-powered devices where power conservation is crucial.

The device's operational characteristics include a large DC voltage gain of 100 dB and a bandwidth of 1.1 MHz, which is suitable for applications such as transducer amplifiers, DC gain blocks, and all the conventional op-amp circuits. Furthermore, the LM358ADT can drive loads to within 1.5V of the power supply voltage boundaries, enhancing its efficiency in single-supply operations.

STMicroelectronics ensures that the LM358ADT maintains its reliability and performance across a wide operating temperature range, from -40°C to +105°C. This makes it a robust component suitable for industrial, automotive, and consumer applications. The device also includes internal frequency compensation, which simplifies its use by eliminating the need for external components.

Overall, the LM358ADT is a practical solution for designers looking for a general-purpose op-amp that is easy to use and provides stable operation for a wide array of electronic circuits. Its combination of low power, high gain, and versatile supply voltage range makes it a go-to component for both hobbyists and professional engineers alike.
