BD12734FJ-GE2

Overview

The BD12734FJ-GE2 is a quad-channel operational amplifier manufactured by ROHM Semiconductor. It operates on a single supply voltage ranging from 1.8 V to 5.5 V and supports an operating temperature range of -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 a typical supply current of 1.2 mA with four channels active and provides an output current of 12 mA per channel. It features low input-referred noise voltage of 10 nV/√Hz, high phase margin, and full input/output swing capabilities.

Feature Summary

• Input and output full swing capability for extended dynamic range
• Low supply current consumption suitable for battery-powered systems
• High phase margin ensuring stable operation without oscillation
• Low input-referred noise voltage for precision signal processing

Applications

• Audio applications requiring low noise performance
• Battery management systems
• General-purpose analog signal conditioning

Procurement Notes

Verify the specific suffix 'FJ' corresponds to the SOP-J8 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets. Ensure the ordering quantity matches the standard taping packaging requirements specified in the official data sheet to avoid handling discrepancies.

Selection Notes

Select this component when a quad-channel configuration is required within a compact SOP-J8 footprint. It is appropriate for designs needing rail-to-rail output swing with minimal power draw. Compare against dual-channel variants like the BD12732 series if fewer channels suffice. Verify that the 1 MHz bandwidth meets the signal frequency requirements of the target application circuit.

Part Context

This part belongs to the BD1273x series of low supply current operational amplifiers from ROHM Semiconductor. The series includes single (BD12730), dual (BD12732), and quad (BD12734) channel options. These devices are designed for portable electronics where low voltage operation and energy efficiency are critical constraints.

Replacement Considerations

Check for direct pin-compatible substitutes within the same BD1273x family, such as the BD12734FV-E2, noting differences in package type (TSSOP-B14 vs SOP-J8). Verify functional equivalence regarding supply voltage ranges and electrical parameters before substitution.
