Overview
The BD12732FJ-GE2 is a dual-channel operational amplifier manufactured by ROHM Semiconductor, housed in an SOP-J8 package. It operates on a single supply voltage ranging from 1.8 V to 5.5 V with a typical supply current of 580 µA per channel. 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 features low input noise density of 10 nV/√Hz, high phase margin, and full input/output swing capabilities within the operating temperature range of -40°C to +85°C.
Feature Summary
- Input and output full swing capability for maximum dynamic range utilization
- Low supply current consumption suitable for battery-powered applications
- High phase margin ensuring stable operation without oscillation
- Low equivalent input noise voltage for high-fidelity signal processing
Applications
- Audio equipment signal conditioning
- Battery management systems
- General-purpose analog signal amplification
Procurement Notes
Verify the specific suffix 'GE2' against the manufacturer's latest datasheet to confirm RoHS compliance and packaging details. Ensure the SOP-J8 pinout matches the target PCB footprint design. Confirm that the 1.8 V minimum supply voltage aligns with the system power rails. Check for any obsolescence notices or recommended replacement parts from ROHM before finalizing procurement.
Selection Notes
Select this component when low power consumption and rail-to-rail performance are required within a 5.5 V limit. The dual-channel configuration reduces board space compared to single op-amps. Consider the 1 MHz bandwidth and 400 mV/µs slew rate for audio-frequency applications. Verify that the 1 mV input offset voltage meets the precision requirements of the specific circuit design.
Part Context
This part belongs to the BD1273x series of low supply current input/output full swing operational amplifiers from ROHM. The series includes single (BD12730G), dual (BD12732), and quad (BD12734) variants sharing similar electrical characteristics. The BD12732FJ-GE2 specifically denotes the dual-channel version in the SOP-J8 package with tape-and-reel packaging options.
Replacement Considerations
Consult ROHM documentation for direct cross-reference models within the BD1273x family. Verify pin compatibility and electrical parameter equivalence before substituting with other manufacturers' dual op-amps.
