Overview
The BA14741F-E2 is a quad operational amplifier manufactured by ROHM Semiconductor, housed in a 14-pin SOP package. It features four independent channels with a maximum input offset voltage of 5000 uV. The device operates within a supply voltage range of 2 to 18 volts and draws a typical quiescent current of 3 mA per channel. Input bias current is specified at 60 nA. It supports standard differential input configurations and includes internal phase compensation.
Feature Summary
- Quad-channel architecture providing four independent operational amplifiers in a single package
- Low input offset voltage specification for precision signal processing applications
- Wide single-supply operating voltage range supporting flexible power design options
- Internal phase compensation eliminating the need for external frequency stabilization components
Applications
- General-purpose analog signal conditioning circuits
- Audio pre-amplification stages requiring low noise performance
- Sensor interface circuits for transducer signal amplification
- Active filter implementations in measurement equipment
Procurement Notes
Verify the specific suffix E2 against the manufacturer's latest datasheet to confirm compliance with current RoHS directives and material declarations. Ensure the ordering code matches the required SOP-14 package variant. Confirm availability status as distribution listings may vary. Validate that the component meets the environmental specifications required for the target application before finalizing procurement orders.
Selection Notes
Select this component when a quad configuration is required to minimize board space compared to individual dual amplifiers. Consider the 60 nA input bias current for high-impedance source applications. Evaluate the 5000 uV offset voltage limit against system accuracy requirements. Verify that the 3 mA per channel current consumption aligns with thermal management constraints in the final enclosure design.
Part Context
This part belongs to ROHM's BA series of operational amplifiers, which are designed for general-purpose analog applications. The BA14741 family offers multiple package options including PDIP and SOP variants. The F-E2 designation specifically indicates the surface-mount SOP-14 package with lead-free compliant manufacturing processes suitable for automated assembly.
Replacement Considerations
Publicly confirmed substitute part numbers include BA14741AF, BA14741FE1, and BA14741FT1. These variants share the same quad op-amp functionality but may differ in packaging or specific electrical tolerances. Verify pin compatibility and parameter limits before substitution.
