The LM358WN from STMicroelectronics is a dual operational amplifier (op-amp) that is designed for a wide range of analog applications. This versatile chip is a part of the LMx58 series, which are low-power, dual operational amplifiers intended for use in consumer, industrial, and scientific devices.

Featuring two independent, high-gain, internally frequency-compensated op-amps, the LM358WN is optimized for single supply operations and can operate at voltages as low as 3V, up to 32V. The low supply-current drain is independent of the magnitude of the power supply voltage, which makes the LM358WN an excellent choice for battery-powered devices.

Key Features

• Supply Voltage Range: 3V to 32V for single supply, or ±1.5V to ±16V for dual supply operations.
• Low Supply Current Drain: 700 µA—Essentially independent of supply voltage.
• Common Mode Input Voltage Range: Includes ground, making the device suitable for ground-referenced sensors.
• Differential Input Voltage Range: Equal to the power supply voltage.
• Large Output Voltage Swing: 0V to V_CC - 1.5V.
• Internally Frequency Compensated: No external components required.
• Low Input Bias and Offset Parameters: Ensures accuracy in linear applications.

Applications

The LM358WN is suitable for a variety of applications, including:

• Transducer amplifiers
• DC gain blocks
• Conventional operational amplifier circuits
• Analog signal conditioning
• Active filters
• General-purpose amplification

With its robust design and proven reliability, the LM358WN is a staple in the toolkit of engineers and designers who require a dependable dual operational amplifier for their analog circuits. STMicroelectronics' commitment to quality ensures that this op-amp meets the stringent requirements of the most demanding applications.
