BD12734FVJ-E2

Overview

The BD12734FVJ-E2 is a four-channel operational amplifier manufactured by ROHM Semiconductor, housed in a TSSOP-14 surface-mount package. It operates within a supply voltage range of 1.8 V to 5.5 V with a typical quiescent current of 1.2 mA. Key electrical parameters include a gain-bandwidth product of 1 MHz, a slew rate of 400 mV/µs, and an input offset voltage of 1 mV. The device supports an output current of 12 mA per channel and features low noise characteristics with an input voltage noise density of 10 nV/√Hz.

Feature Summary

• Low supply current operation suitable for battery-powered applications
• Input and output full swing capability across the operating voltage range
• Low equivalent input noise voltage for signal integrity
• High phase margin ensuring stable performance

Applications

• Battery-operated electronic devices
• Audio equipment signal processing
• General-purpose analog signal conditioning

Procurement Notes

Verify the specific suffix E2 against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Ensure the TSSOP-14 package dimensions match your PCB footprint requirements. Confirm that the 1.8 V minimum supply voltage aligns with your system's power rails before finalizing procurement.

Selection Notes

Select this component when low power consumption is critical alongside rail-to-rail output requirements. The 1 MHz bandwidth suits moderate-speed applications but may be insufficient for high-frequency signal processing. Consider the 1 mV input offset voltage for precision needs, as higher accuracy parts may require different specifications.

Part Context

This part belongs to ROHM's low supply current operational amplifier series. It is designed as a general-purpose solution for portable electronics where power efficiency and full-swing output are prioritized over high-speed performance. The four-channel configuration allows for multiple signal paths in a single compact package.
