BA3474RFV-E2

Overview

The BA3474RFV-E2 is a high-speed operational amplifier manufactured by ROHM Semiconductor, featuring four independent channels in an SSOP-14 package. It operates within a supply voltage range of 3 V to 36 V and supports ground sensing input. Key electrical parameters include a gain-bandwidth product of 4 MHz, a slew rate of 10 V/µs, and a typical open-loop voltage gain of 100 dB. The device provides an output current of 30 mA per channel with a maximum operating temperature of +105°C.

Feature Summary

• Supports single-supply operation with wide voltage range from 3 V to 36 V
• Features ground-sense capability allowing common-mode input voltage to include the ground level
• Includes built-in phase compensation capacitors for stability without external components

Applications

• Industrial signal conditioning circuits requiring ground-referenced inputs
• Sensor interface applications utilizing wide dynamic range amplification
• General-purpose high-speed analog processing in industrial environments

Procurement Notes

Verify the component status as Not Recommended for New Designs (NRND) before finalizing any procurement strategy. Confirm that the SSOP-B14 package dimensions align with existing PCB footprints. Ensure compliance with RoHS directives by checking the specific manufacturing batch documentation. Validate that the -40°C to +105°C operating temperature range meets the environmental requirements of the target application.

Selection Notes

Select this component when a quad-channel configuration is required alongside high-speed performance characteristics. The 4 MHz gain-bandwidth product and 10 V/µs slew rate suit moderate-frequency signal processing tasks. Consider the 30 mA output drive capability for direct interfacing with low-impedance loads. The wide supply voltage tolerance simplifies power design across various industrial voltage rails.

Part Context

This part belongs to the BA3474 series of high-speed operational amplifiers designed for robust industrial performance. It shares architectural similarities with other members like the BA3472F-E2 but offers four channels instead of two. The device integrates standard op-amp terminal connections and internal phase compensation, distinguishing it from general-purpose amplifiers that may require external stabilization components.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should evaluate alternative quad-channel amplifiers from the same manufacturer or compatible families if sourcing becomes difficult due to the NRND status.
