BD12732FVM-GTR

Overview

The BD12732FVM-GTR is a dual-channel operational amplifier manufactured by ROHM Semiconductor, designed for low supply current applications. It features a gain-bandwidth product of 1 MHz and a slew rate of 400 mV/us. The device operates within a power supply range of 1.8 V to 5.5 V with a typical operating current of 580 uA. Key electrical parameters include an input offset voltage of 1 mV, input bias current of 50 nA, and output current capability of 12 mA per channel. It offers a common-mode rejection ratio of 55 dB and a power supply rejection ratio of 70 dB. The component is housed in an MSOP-8 package and functions across a temperature range of -40°C to +85°C.

Feature Summary

• Input and output full swing operation allows signal rails to extend from the negative supply to near the positive supply voltage.
• Low supply current consumption design supports extended battery life in portable electronic devices.
• High phase margin ensures stable performance without oscillation in various feedback configurations.

Applications

• Battery-powered consumer electronics requiring low quiescent current
• Audio equipment utilizing low-noise amplification characteristics
• General-purpose signal conditioning in single-supply systems

Procurement Notes

Verify the specific suffix GTR against the manufacturer's official documentation to confirm tape-and-reel packaging specifications. Ensure the part number matches the exact MSOP-8 variant required for your PCB footprint. Cross-reference the RoHS compliance status directly with the latest datasheet revision. Confirm that the operating temperature range aligns with your system's environmental requirements before finalizing procurement orders.

Selection Notes

Select this component when a dual-channel op amp with rail-to-rail output is needed under a 5.5 V maximum supply constraint. It is suitable for designs prioritizing low power consumption over high-speed performance. Compare its 1 MHz bandwidth against higher-speed alternatives if signal fidelity at elevated frequencies is critical. Ensure the 12 mA output drive capability meets the load requirements of the downstream circuitry.

Part Context

This part belongs to the BD12732 series of low supply current operational amplifiers. It shares architectural similarities with the BD12734FVJ-E2 but differs in channel count and package type. The FVM designation indicates the MSOP-8 surface-mount package, distinguishing it from other form factors in the family. It serves as a general-purpose amplifier for cost-sensitive and space-constrained applications.
