CA5260T

Overview

The CA5260T is a dual operational amplifier manufactured by Harris Corporation, integrating CMOS and bipolar transistors on a monolithic chip. It features a MOSFET input stage providing very high input impedance of 1.5 TΩ (typical) and low input bias current of 5 pA (typical) at 15V operation. Designed for +5V supply systems, it operates from -55°C to +125°C with full military temperature range guarantees. The device supports single-supply applications with common-mode input voltage including the negative rail.

Feature Summary

• MOSFET input stage provides very high input impedance and low input bias current
• CMOS output stage permits signal swing to either or both supply rails
• Common mode input voltage range includes negative supply rail

Applications

• Ground referenced single supply amplifiers
• Fast sample-hold amplifiers
• Long duration timers and monostables
• Ideal interface with digital CMOS
• High input impedance wideband amplifiers

Procurement Notes

Verify manufacturer authenticity as Harris Corporation assets were acquired. Confirm package type matches original specifications. Check RoHS compliance status if required for modern assembly. Validate operating temperature range against application requirements. Ensure supply voltage compatibility with system design.

Selection Notes

Select this component for applications requiring high input impedance and single-supply operation. Suitable for interfacing with digital CMOS logic systems. Ideal for ground-referenced amplification where signal swing to supply rails is necessary. Consider thermal performance within the guaranteed -55°C to +125°C range.
