BD12732FVT-GE2

Overview

The BD12732FVT-GE2 is a dual-channel operational amplifier from ROHM Semiconductor, designed for low supply current and full input/output swing applications. It operates on a single supply voltage ranging from 1.8 V to 5.5 V. 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 draws a typical operating current of 580 µA per channel and provides an output current of 12 mA. It features a common-mode rejection ratio of 55 dB and an input voltage noise density of 10 nV/√Hz. The component is housed in an SSOP-8 package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Input and output full swing capability allows signal rails to approach the power supply limits.
• Low operating supply voltage enables efficient performance in battery-powered systems.
• High phase margin ensures stability without requiring external compensation components.
• Low equivalent input noise voltage supports high-fidelity signal processing.

Applications

• Battery management systems
• Audio equipment signal conditioning
• General-purpose analog circuit design

Procurement Notes

Verify the specific suffix 'GE2' against the manufacturer's latest documentation to confirm RoHS compliance status and exact pinout configuration. Ensure the SSOP-8 package dimensions match the target PCB footprint requirements. Confirm that the operating temperature range meets the environmental constraints of the final assembly. Cross-reference the ordering part number with official distributor catalogs to avoid counterfeit components.

Selection Notes

Select this component when a dual-channel op-amp with rail-to-rail output is required under low voltage conditions. It is suitable for designs prioritizing low power consumption alongside adequate bandwidth for audio or sensor interfaces. Consider the 12 mA output drive capability for driving moderate loads directly. Evaluate the 1 mV input offset voltage against the precision requirements of the specific application circuit.

Part Context

This device belongs to the BD12732 series of low supply current operational amplifiers. The series includes variants such as the BD12730G (single) and BD12734 (quad). The BD12732FVT-GE2 specifically denotes the dual-channel version in a TSSOP-B8 or SSOP-8 compatible package with tape-and-reel packaging. It shares core electrical characteristics with other members of the family while differing in channel count and physical package geometry.

Replacement Considerations

Consult official substitution guides for direct replacements. Potential alternatives may include other dual-channel op-amps with similar 1 MHz bandwidth and low supply current profiles, provided they support the required 1.8 V minimum operating voltage and full-swing output characteristics.
