BD12732FV-GE2

Overview

The BD12732FV-GE2 is a dual-channel operational amplifier manufactured by ROHM Semiconductor, housed in an SSOP-8 surface-mount package. It operates on a single supply voltage ranging from 1.8 V to 5.5 V with a typical supply current of 580 µA. Key electrical specifications 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 features low input bias current (50 nA) and low input voltage noise density (10 nV/√Hz). It supports output currents up to 12 mA per channel and maintains operation within a temperature range of -40°C to +85°C.

Feature Summary

• Input/output full swing capability for maximum dynamic range
• Low supply current consumption suitable for battery-powered devices
• Low equivalent input noise voltage for high-fidelity signal processing
• High phase margin ensuring stable operation without oscillation

Applications

• Audio applications requiring low noise performance
• Battery management systems utilizing low voltage operation
• General purpose analog signal conditioning circuits

Procurement Notes

Verify the specific suffix GE2 confirms the SSOP-8 package and tape-and-reel or cut-tape availability as listed by authorized distributors. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the ordering code matches the exact pinout and thermal characteristics required for the target PCB layout design.

Selection Notes

Select this component when designing circuits that require rail-to-rail input and output swing under low voltage conditions. It is appropriate for applications demanding low power consumption alongside moderate bandwidth requirements. Consider the SSOP-8 footprint constraints and the specific noise floor requirements relative to other op-amps in the BD1273x family.

Part Context

This part belongs to the BD1273x series of low supply current input/output full swing operational amplifiers from ROHM. The series includes single (BD12730G), dual (BD12732xxx), and quad (BD12734xxx) variants. These amplifiers are engineered for portable electronics where power efficiency and signal integrity are critical, offering a balance of speed and low quiescent current.

Replacement Considerations

Direct functional substitutes within the same family include BD12732FJ-GE2 (SOP-J8 package) and BD12732FV (standard SOP-8 package). Verify pin compatibility and package dimensions before substitution. Cross-reference with other dual-channel low-voltage op-amps if package changes are acceptable.
