CA5260AT

Instrumentation, Op Amps, Buffer Amps Overview

The CA5260AT is a dual BiMOS microprocessor operational amplifier featuring MOSFET input and CMOS output stages. It combines high input impedance with rail-to-rail output swing, designed for +5V logic systems. The device operates on supply voltages from 4.5V to 16V or ±2.25V to ±8V split supplies. It guarantees specifications over the full military temperature range of -55°C to +125V at V+ = 5V.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• MOSFET input stage provides very high input impedance and very low input bias current
• CMOS output stage permits signal swing to either or both supply rails
• Common-mode input voltage range includes the negative supply rail
• Guaranteed operation down to 4.5V for open-loop gain

Instrumentation, Op Amps, Buffer Amps Applications

• Ground referenced single supply amplifiers
• Fast sample-hold amplifiers
• High input impedance wideband amplifiers
• Voltage followers for single supply D/A converters
• Photo diode sensor amplifiers

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the suffix 'AT' against official Intersil/Renesas documentation to confirm specific package type, temperature grade, or tape-and-reel configuration. Ensure the component matches the required military temperature range (-55°C to +125°C) and that the datasheet explicitly supports the 'AT' designation for the CA5260 series.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when interfacing with digital CMOS logic requiring high input impedance and rail-to-rail output capability. It is suitable for applications needing guaranteed performance at 5V supplies within the military temperature range. Consider the BiMOS technology for its combination of speed and low input current compared to standard bipolar or pure CMOS op-amps.

Instrumentation, Op Amps, Buffer Amps Part Context

The CA5260 series are dual versions of the popular CA5160 series. They integrate CMOS and bipolar transistors on a monolithic chip. The series is designed for microprocessor or logic systems using +5V supplies. Gate-protected P-Channel MOSFETs are used in the input circuit for exceptional speed and high impedance.
