CA3240E

Overview

The CA3240E is a dual BiMOS operational amplifier featuring PMOS input transistors and bipolar output stages. It offers a gain-bandwidth product of 4.5 MHz and a slew rate of 9 V/us. Key electrical parameters include an input bias current of 40 pA, input offset voltage of 5 mV, and supply current of 8 mA per channel. The device supports dual supply voltages from 2 V to 18 V or single supplies from 4 V to 36 V. It provides 40 mA output current capability and operates within a temperature range of -40°C to +85°C in an 8-pin PDIP package.

Feature Summary

Combines high input impedance gate-protected PMOS inputs with high-current bipolar outputs on a monolithic chip.
Provides a wide common-mode input voltage range extending typically to 0.5V below the negative supply rail.
Compatible with industry standard 1458 operational amplifiers in similar packages.

Applications

General-purpose analog signal processing circuits
High-impedance sensor interface applications
Audio pre-amplification stages

Procurement Notes

Verify the specific manufacturer designation as Renesas Electronics Corporation, which acquired Intersil. Confirm the RoHS compliance status through official datasheets. Ensure the 8-PDIP package matches the target PCB footprint. Check for obsolescence notices as some variants may be discontinued.

Selection Notes

Select this component when high input impedance and low bias current are required alongside moderate bandwidth. The BiMOS technology allows for wider common-mode voltage ranges compared to standard bipolar op-amps. Consider the 8-PDIP package for through-hole assembly requirements.

Part Context

The CA3240E belongs to the CA3240 series, which are dual versions of the popular CA3140 series integrated circuit operational amplifiers. This family combines the advantages of MOS and bipolar transistors on the same monolithic chip to provide both high input impedance and high output current capability.
