Overview
The BA2115FVM-TR is a dual-channel low-noise operational amplifier manufactured by ROHM Semiconductor. It operates within a supply voltage range of 2 V to 14 V and features a gain-bandwidth product of 12 MHz with a slew rate of 4 V/µs. The device draws 3.5 mA of supply current and offers an input bias current of 150 nA. It is housed in an MSOP-8 surface-mount package and supports an operating temperature range from -40°C to +85°C.
Feature Summary
- Dual-channel architecture providing two independent low-noise amplification circuits in a single compact package.
- Low noise performance characterized by a voltage noise density of 7 nV/sqrt Hz for high-fidelity signal processing.
- Wide single-supply operation capability ranging from 2 V to 14 V, accommodating various system power rails.
Applications
- Audio signal conditioning and pre-amplification stages
- Precision sensor interface circuits
- Active filter implementations
Procurement Notes
Verify the specific suffix and packaging configuration against the manufacturer's latest datasheet before ordering. Confirm that the MSOP-8 footprint matches the target PCB layout dimensions. Check for any end-of-life or not-for-new-design status updates directly from ROHM Semiconductor documentation to ensure long-term availability for production.
Selection Notes
Select this component when a dual-op-amp solution is required with low noise specifications and wide supply voltage flexibility. Ensure the application does not demand rail-to-rail output swing, as the specified output range is limited to Vee+0.3 V and Vcc-0.3 V. Verify that the 150 nA input bias current meets the impedance requirements of the source circuit.
Part Context
This part belongs to the BA2115 series of low-noise operational amplifiers. It shares functional characteristics with other variants in the family but is distinguished by its MSOP-8 surface-mount package and tape-and-reel delivery format. The device is designed for applications requiring multiple amplification channels with minimal noise contribution.
Replacement Considerations
Consult official substitution guides for pin-compatible alternatives if this part is discontinued. Verify electrical parameter equivalence for gain-bandwidth, noise density, and supply voltage ranges before implementing any cross-reference component.
