CA3260AE

Instrumentation, Op Amps, Buffer Amps Overview

The CA3260AE 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 offset voltage maximum of 5mV for the CA3260A variant. The device provides high input impedance of 1.5TΩ and low input current of 5pA at 15V operation.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• PMOS input stage delivers very high input impedance and extremely low input bias current.
• CMOS output stage enables signal swing to within 10mV of either supply rail under high load impedance conditions.
• Common mode input voltage range extends down to 0.5V below the negative supply terminal, supporting single-supply applications.

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

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm RoHS compliance status by checking for the 'Z' suffix in the part number, as standard versions may not be compliant. Ensure handling procedures account for electrostatic discharge sensitivity inherent to MOSFET input structures.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high input impedance and rail-to-rail output capability are required in a dual op-amp configuration. The CA3260A variant offers superior input characteristics compared to the standard CA3260. Consider the -55°C to +125°C operating temperature range for industrial environments.

Instrumentation, Op Amps, Buffer Amps Part Context

The CA3260 series integrates both CMOS and bipolar transistors on a monolithic chip. It serves as the dual version of the popular CA3160 series. The package is an 8-lead Dual-In-Line Plastic Package (PDIP) with a lead pitch of 2.54mm.
