BA3474FV-E2

Overview

The BA3474FV-E2 is a high-speed operational amplifier manufactured by ROHM Semiconductor, featuring four independent channels in an SSOP-B14 package. It operates on a single power supply ranging from 3 V to 36 V or dual supplies of ±1.5 V to ±18 V. Key electrical parameters include a gain-bandwidth product of 4 MHz, a slew rate of 10 V/µs, and a maximum input offset voltage of 1 mV. The device draws 8 mA of operating current and provides 30 mA output current per channel with a common-mode rejection ratio of 60 dB.

Feature Summary

Supports full DC brushless fan control applications
Features ground-sense capability for direct detection
Includes built-in phase compensation capacitors

Applications

Full DC brushless fan control systems
Single-phase motor drive circuits
High-speed signal processing requiring ground sensing

Procurement Notes

Verify the lifecycle status before procurement as this component is marked NRND (Not Recommended for New Designs). Confirm that existing inventory meets project requirements since new design adoption is discouraged. Ensure compatibility with the SSOP-14 surface mount package and validate that the specified operating temperature range of -40°C to +85°C aligns with system thermal constraints.

Selection Notes

Select this component when designing for single-supply operation within the 3 V to 36 V range. Consider its high slew rate and gain-bandwidth product for applications requiring fast response times. Verify that the differential input type and ground-sense feature meet the specific signal conditioning needs of the target circuit architecture.

Part Context

This part belongs to the BA3474FV series of high-speed operational amplifiers. It is designed for general-purpose analog signal processing where speed and wide voltage operation are critical. The manufacturer indicates it is produced to support existing customers rather than for new design integration.
