  • What is the difference between CMOS and bipolar opamps?
    • Key advantages of CMOS opamps include extremely small input bias current (on the order of pA) and low power consumption. However, the CMOS process features low withstand voltage, making them suitable for low supply voltage applications. Although bipolar opamps provide higher input bias current and current consumption, they offer higher withstand voltage, low noise, low offset, and wide bandwidth.
  • What is the difference in usage between single and dual supply opamps?
    • In general, a single supply opamp operates by supplying VCC (VDD) to the 0V (ground) reference, while a dual supply opamp is used by supplying a positive voltage to VCC as a reference (ground) and negative voltage to VEE. If the input voltage does not exceed the common mode input voltage range either type can be used. Select a single or dual supply type from the dynamic input/output voltage ranges.
