Overview
The CA5260E is a dual BiMOS microprocessor operational amplifier featuring MOSFET input and CMOS output stages. It operates on single +5V supplies or split rails from ±2.25V to ±8V. The device offers a 3MHz bandwidth, 1.5TΩ typical input impedance, and 5pA typical input bias current at 15V. Output voltage swings within 10mV of supply rails. It supports common-mode input voltages down to 0.5V below the negative rail and functions reliably across the -55°C to 125°C military temperature range.
Feature Summary
- BiMOS architecture combining PMOS input for high impedance with CMOS output for rail-to-rail swing
- Designed specifically for microprocessor and logic systems using +5V supplies
- Input terminals can be swung 0.5V below the negative supply rail
Applications
- Microprocessor interface circuits
- Logic system signal conditioning
- Single-supply analog applications
Procurement Notes
Verify the specific suffix 'E' against manufacturer documentation to confirm package type and temperature grade. Ensure compatibility with +5V logic levels if used in digital-analog interfaces. Confirm availability through authorized distributors as this component may be legacy.
Selection Notes
Select this part when high input impedance and low bias current are required in a single-supply environment. It serves as a dual version of the CA5160 series. Consider the 3MHz bandwidth limit for speed requirements. Verify that the 10mV output saturation meets load impedance conditions.
Part Context
The CA5260 series integrates CMOS and bipolar transistors on a monolithic chip. It is the dual counterpart to the CA5160 series. The design targets applications requiring exceptional speed performance and high input impedance in standard logic supply environments.
FAQ
Can the input voltage go below the negative supply rail?
Yes, the common-mode input voltage capability extends down to 0.5V below the negative-supply terminal.
What is the typical input bias current at 5V operation?
The typical input bias current is 2pA at 5V operation.
