The LM358EDT from STMicroelectronics is a low-power, dual operational amplifier designed to operate from a single power supply over a wide range of voltages. This versatile op-amp is housed in a compact SO-8 package and is a popular choice for a multitude of electronic applications, including transducer amplifiers, DC gain blocks, and all the conventional op-amp circuits that now can be more easily implemented in single power supply systems.

Key Features

• Internally frequency-compensated for unity gain
• Large DC voltage gain: 100 dB
• Wide bandwidth (unity gain): 1.1 MHz (temperature compensated)
• Very low supply current per channel essentially independent of supply voltage
• Low input bias current: 20 nA (temperature compensated)
• Low input offset voltage: 2 mV and offset current: 2 nA
• Input common-mode voltage range includes ground
• Differential input voltage range equal to the power supply voltage
• Low output saturation voltage: 0.2 V at 10 mA
• Output voltage can swing to within a few millivolts of the supply voltage
• Power supply range: Single supply 3V to 32V or dual supplies ±1.5V to ±16V

Applications

The LM358EDT is ideal for sensor interfaces, battery-powered devices, and other applications requiring low power consumption and space-saving design. Its ability to operate on a single power supply simplifies circuit design and reduces power supply requirements. Typical applications include:

• Two-stage amplifiers
• Active filters
• General signal conditioning and amplification
• Charge amplifiers for piezoelectric transducers
• Analog adders or subtractors
• Voltage followers
• Integrators and differentiators
