output short circuit protection and latch-free operation.
These types also feature wide common mode and • DC Amplifier
differential mode signal ranges and have low offset voltage • Summing Amplifier
nulling capability when used with an appropriately valued
potentiometer. A 10k potentiometer is used for offset • Integrator or Differentiator
nulling types CA741C, CA741 (see Figure 1). Types • Narrow Band or Band Pass Filter
CA1458, CA1558 have no specific terminals for offset
nulling. Each type consists of a differential input amplifier Ordering Information
