BA2902SF-E2

Overview

The BA2902SF-E2 is a quad operational amplifier manufactured by ROHM Semiconductor, housed in a 14-pin SOP 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 characteristics include a gain-bandwidth product of 500 kHz, a slew rate of 0.2 V/µs, and an input offset voltage maximum of 7 mV. The device draws a typical circuit current of 0.175 mA per channel and supports an output current of 30 mA. It functions within a temperature range of -40°C to 105°C.

Feature Summary

• Supports single-supply operation with wide voltage range
• Allows input and output signals to operate near ground level
• Includes built-in phase compensation capacitors

Applications

• General-purpose analog signal processing circuits
• Low-voltage sensor interface applications
• Battery-powered equipment requiring low quiescent current

Procurement Notes

Verify the specific suffix E2 for RoHS compliance and lead time requirements. Confirm availability status as this component may be subject to discontinuation or lifecycle changes. Ensure the SOP-14 package dimensions match your PCB footprint design constraints before finalizing procurement orders.

Selection Notes

Select this component when a quad amplifier configuration is required with ground-sense capabilities. It is suitable for designs needing low power consumption without sacrificing basic bandwidth. Consider the 7 mV offset voltage limit for precision requirements and verify thermal dissipation limits for high ambient temperatures.

Part Context

This part belongs to the BA2902 series of general-purpose operational amplifiers. It shares functional similarities with other members like the BA2901 and BA2903 but differs in channel count and specific package options. The SF suffix typically denotes the SOP-14 surface-mount package variant.
