BD12734F-GE2

Overview

The BD12734F-GE2 is a quad-channel operational amplifier manufactured by ROHM Semiconductor, housed in a SOP-14 surface-mount package. It operates within a supply voltage range of 1.8 V to 5.5 V and supports an operating temperature range from -40°C to +85°C. Key electrical specifications include a gain-bandwidth product of 1 MHz, a slew rate of 400 mV/µs, and a maximum input offset voltage of 1 mV. The device draws 1.2 mA of operating supply current and provides 12 mA output current per channel. Additional parameters feature a common-mode rejection ratio of 55 dB, a power supply rejection ratio of 70 dB, and an input voltage noise density of 10 nV/√Hz.

Feature Summary

• Input/output full swing capability allows signal rails to approach the supply voltage limits.
• Low supply current consumption design suitable for battery-powered applications.
• Low input referred noise voltage ensures high-fidelity signal processing.
• High phase margin provides stable operation without external compensation.

Applications

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

Procurement Notes

Verify the specific suffix 'F-GE2' against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS compliance status. Ensure the SOP-14 package dimensions match the target PCB footprint. Confirm that the required operating temperature range aligns with the specified -40°C to +85°C limit for the intended environment.

Selection Notes

Select this component when a quad-channel configuration is required alongside low noise performance and rail-to-rail output swing. Compare total supply current against dual-channel alternatives if space or channel count permits optimization. Verify that the 1 MHz bandwidth meets the signal frequency requirements and that the 1 mV max offset voltage satisfies precision needs.

Part Context

This part belongs to the BD1273x series of low supply current operational amplifiers from ROHM. The series includes single (BD12730G), dual (BD12732xxx), and quad (BD12734xxx) variants sharing similar electrical characteristics such as low noise and full-swing outputs. The BD12734F-GE2 represents the four-channel version optimized for compact surface-mount integration.

Replacement Considerations

Cross-reference with other members of the BD1273x family, such as the BD12732 series for dual-channel needs. Verify functional equivalence regarding supply voltage, channel count, and package type before substitution.
