BD12732F-GE2

Overview

The BD12732F-GE2 is a dual-channel operational amplifier manufactured by ROHM Semiconductor, designed for low supply current and full input/output swing applications. It operates within a voltage range of 1.8 V to 5.5 V and features a gain-bandwidth product of 1 MHz with a slew rate of 400 mV/us. Key electrical parameters include an input offset voltage of 1 mV, input bias current of 50 nA, and typical supply current of 580 uA per channel. The device offers high phase margin (75° typ), low input noise density (10 nV/√Hz), and CMRR of 55 dB. It supports output currents up to 12 mA per channel and functions reliably across temperatures from -40°C to +85°C in SOP-8 packages.

Feature Summary

• Input and output full swing capability allows signal processing near power rails.
• Low supply current design optimizes battery life in portable devices.
• High phase margin ensures stability without external compensation components.
• Low input referred noise voltage supports high-fidelity audio applications.

Applications

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

Procurement Notes

Verify the specific suffix 'GE2' against the manufacturer's latest datasheet to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements for your target market. Confirm that the SOP-8 package dimensions align with your PCB footprint design rules before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring rail-to-rail performance on both inputs and outputs under single-supply conditions. It is suitable for applications where low power consumption is critical but moderate bandwidth is sufficient. Consider the 1 mV input offset voltage for precision requirements and verify thermal dissipation capabilities within the specified operating temperature range.

Part Context

This part belongs to the BD12732 series of low supply current input/output full swing operational amplifiers. It shares architectural similarities with the BD12730G (single) and BD12734 (quad) variants, offering consistent electrical characteristics across different channel counts. The series is optimized for consumer electronics and battery-operated devices requiring efficient power usage.

Replacement Considerations

Direct substitutes may include other dual-channel op-amps with similar 1 MHz GBP and rail-to-rail I/O specifications. Verify pin compatibility and electrical parameter overlaps such as supply current and noise density before substitution.
