LM358H

The LM358H is a dual operational amplifier (op-amp) manufactured by Texas Instruments, designed for a variety of analog signal processing applications. It is particularly well-suited for low-frequency applications due to its low noise and low distortion characteristics.

Key Features:

1. Dual Op-Amp Configuration: The LM358H contains two independent, high-gain, frequency-compensated operational amplifiers. This allows for versatile circuit designs, enabling users to implement multiple functions such as amplification, filtering, and signal conditioning within a single package.

2. Supply Voltage Range: The device operates over a wide supply voltage range, typically from 3V to 32V for single supply operation, or ±1.5V to ±16V for dual supply operation. This flexibility makes it suitable for battery-powered applications as well as standard power supply circuits.

3. Low Input Offset Voltage: The LM358H features a low input offset voltage, typically around 2mV, which enhances accuracy in applications requiring precise signal amplification.

4. High Gain: The op-amp provides a high open-loop gain of approximately 100 dB, ensuring that even small input signals can be amplified effectively.

5. Wide Bandwidth: With a unity-gain bandwidth of around 1 MHz, the LM358H can handle a variety of signal frequencies, making it suitable for audio and other low-frequency applications.

6. Low Power Consumption: The device is designed for low power operation, making it ideal for portable and battery-operated devices. The quiescent current is typically around 0.5 mA per amplifier.

7. Temperature Range: The LM358H is rated for operation over a temperature range of -40°C to +125°C, making it suitable for industrial and automotive applications where temperature extremes may be encountered.

8. Package Options: The LM358H is available in various package types, including DIP (Dual In-line Package) and SOIC (Small Outline Integrated Circuit), allowing for easy integration into different circuit designs.

Applications:

The LM358H is widely used in various applications, including:

• Signal conditioning
