Overview
The BD12734FV-GE2 is a low supply current, input/output full swing operational amplifier manufactured by ROHM Semiconductor. It features four channels within a TSSOP-14 package. Key electrical parameters include a gain-bandwidth product of 1 MHz and a slew rate of 400 mV/us. The device operates on a power supply voltage ranging from 1.8 V to 5.5 V with a typical circuit current of 1.2 mA. It exhibits an input offset voltage of 1 mV, input bias current of 50 nA, and input voltage noise density of 10 nV/sqrt Hz. The output can source 12 mA per channel, with a common-mode rejection ratio of 55 dB and power supply rejection ratio of 70 dB.
Feature Summary
- Supports input and output full swing operation for maximum dynamic range.
- Designed for low supply current consumption suitable for battery-powered applications.
- Features low equivalent input noise voltage for high-fidelity signal processing.
Applications
- Battery-operated electronic devices
- Audio equipment signal conditioning
Procurement Notes
Verify the specific suffix GE2 against the manufacturer's datasheet to confirm pinout compatibility and RoHS status. Ensure the TSSOP-14 package dimensions match the target PCB footprint. Confirm that the 1.8 V minimum supply voltage aligns with the system design requirements before finalizing procurement.
Selection Notes
Select this component when a quad-channel op-amp is required with rail-to-rail output capabilities and low power consumption. The 1 MHz bandwidth is sufficient for general-purpose audio and sensor interface applications. Consider the TSSOP-14 package size constraints during layout planning.
Part Context
This part belongs to the BD1273x series of low supply current operational amplifiers from ROHM. The series includes dual (BD12732) and quad (BD12734) variants. These amplifiers are characterized by their ability to operate at low voltages while maintaining full swing input and output ranges, making them distinct from standard single-supply op-amps.
Replacement Considerations
Check for BD12734FV as a potential variant. Verify package compatibility between SSOP-B14 and TSSOP-14 if substituting.
