CA3140AE

Overview

The CA3140AE is a BiMOS operational amplifier featuring a PMOS input stage and bipolar output stage. It operates on supply voltages from 4V to 36V (single or dual). Key electrical parameters include a gain-bandwidth product of 4.5MHz, a slew rate of 9V/µs, and an input bias current of 10pA at ±15V. The device provides very high input impedance of 1.5TΩ and supports common mode input voltage down to 0.5V below the negative rail. It includes internal phase compensation for unity gain stability and offset nulling terminals.

Feature Summary

Integrates PMOS field-effect transistors in the input stage to achieve extremely high input impedance and minimal input bias current.
Features a bipolar transistor output stage with built-in protection against short circuits to ground or supply rails.
Includes dedicated terminals for input offset voltage nulling and supplementary external frequency compensation.

Applications

Ground-referenced single supply amplifiers in automobile and portable instrumentation
Sample and hold amplifiers
Photocurrent instrumentation and peak detectors
Active filters and comparators
Interface in 5V TTL systems

Procurement Notes

Verify that the specific part number matches the required package type and temperature range. Confirm RoHS compliance status if lead-free processing is mandated. Ensure the ordering suffix aligns with the intended manufacturing process, as some variants are restricted to wave soldering only.

Selection Notes

Select this component when high input impedance and low bias current are critical requirements. The wide common mode input range extending below the negative rail makes it suitable for single-supply applications. Verify that the 4.5MHz bandwidth and 9V/µs slew rate meet the signal processing speed requirements.

Part Context

The CA3140AE belongs to the CA3140 series of BiMOS operational amplifiers manufactured by Renesas Electronics Corporation (formerly Intersil/Harris). This series combines the advantages of high-voltage PMOS and bipolar technologies on a single monolithic chip to provide superior performance over standard bipolar op-amps.
