0.9MHz Single and Dual, High Gain Operational Amplifiers for Military, Industrial and Commercial Applications
The CA1458, CA1558 (dual types); CA741C, CA741 (single types); high-gain operational amplifiers for use in military, industrial, and commercial applications. These monolithic silicon integrated circuit devices provide output short circuit protection and latch-free operation. These types also feature wide common mode and differential mode signal ranges and have low offset voltage nulling capability when used with an appropriately valued potentiometer. A 10kΩ potentiometer is used for offset nulling types CA741C, CA741 (see Figure 1).

NOTES: 1. Values apply for each section of the dual amplifiers. 2. All types in any package style can be operated over the temperature range of -55oC to 125oC, although the published limits for certain electrical specification apply only over the temperature range of 0oC to 70oC. 3. θJA is measured with the component mounted on an evaluation PC board in free air.
