CA3260E

Instrumentation, Op Amps, Buffer Amps Overview

The CA3260E is a dual operational amplifier featuring a BiMOS architecture with PMOS input and CMOS output stages. It operates on supply voltages from 4V to 16V or ±2V to ±8V. Key electrical parameters include a unity gain crossover frequency of 4MHz, a slew rate of 10V/µs, and an input resistance of 1.5TΩ. The device supports an operating temperature range of -55°C to +125°C and is housed in an 8-lead PDIP package.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Integrates PMOS input transistors for very high input impedance and low input current
• CMOS output stage enables signal swing to within millivolts of either supply rail
• Common mode input voltage extends 0.5V below the negative supply terminal
• Capable of operation with single supply configurations

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 specific ordering suffix against manufacturer documentation to confirm lead-free status and RoHS compliance. Confirm that the selected package variant meets the intended soldering process requirements, as certain plastic packages are designated for through-hole wave solder processing only and may not be suitable for reflow applications.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high input impedance and fast transient response are required in a dual amplifier configuration. The CA3260A variant offers superior input offset characteristics compared to the standard CA3260. Ensure the application utilizes supply voltages within the specified 4V to 16V range and accommodates the industrial temperature grade.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the CA3260 series, which serves as a dual-channel version of the popular CA3160 single-channel operational amplifier. The series combines the advantages of CMOS and bipolar technologies on a monolithic chip. Intersil, now part of Renesas Electronics Corporation, manufactures these devices utilizing ISO9000 quality systems.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The CA3260AE is a documented alternative within the same series offering improved input characteristics. Verify pinout compatibility and electrical parameter alignment before substitution.
