Dual Operational Amplifier
General Description
• The LM358 series consists of two independent high gain, internally frequency compensated operational amplifiers. It can be operated from a single power supply and also split power supplies.
• The LM358 is available in SOP-8, DIP-8, TSSOP-8 and MSOP-8 packages
Features Applications
• Internally frequency compensated for unity gain
•
Wide power supply range 3V - 32 V
• Input common-mode voltage range include ground
• Large DC voltage gain: 100dB Typical • RoHS Compliance
