LM358 | LM358 IC – Low Power Dual Op

LM358 | LM358 IC – Low Power Dual Op – Application areas include transducer amplifiers, DC gain blocks, and all the conventional op-amp circuits which now can be more easily implemented in single power supply systems. For example, the LM158 series can be directly operated off of the standard 3.3-V power supply voltage which is used in digital systems and will easily provide the required interface electronics without requiring the additional ±15-V power supplies.
The LM358 and LM2904 are available in a chip-sized package (8-bump DSBGA) using TI’s DSBGA package technology.

Features: LM358 IC

• Available in 8-bump DSBGA chip-sized package (see AN-1112, SNVA009)
• Internally frequency compensated for unity gain
• Large DC voltage gain: 100 dB
• Wide bandwidth (unity gain): 1 MHz (temperature compensated)
• Wide power supply range:
  – Single supply: 3 V to 32 V
  – Or dual supplies: ±1.5 V to ±16 V
• Very low supply current drain (500 μA) essentially independent of supply voltage
• Low input offset voltage: 2 mV
• Input common-mode voltage range includes ground
• Differential input voltage range equal to the power supply voltage
• Large output voltage swing
• Unique characteristics:
  – In the Linear Mode the input common-mode
• voltage range includes ground and the output
• voltage can also swing to the ground, even though
• operated from only a single power supply voltage
  – The unity gain cross frequency is temperature compensated
  – The input bias current is also temperature compensated
• Advantages:
  – Two internally compensated op-amps
  – Eliminates the need for dual supplies
  – Allows direct sensing near GND and VOUT also Goes to GND
  – Compatible with all forms of logic
  – Power drain suitable for battery operation

 Applications: LM358 IC

• Active filters
• General signal conditioning and amplification
• 4-mA to 20-mA current loop transmitters
