Overview
The BA2902SFV-E2 is a standard ground sense operational amplifier manufactured by ROHM Semiconductor. It features four channels in an SSOP-B14 package with dimensions of 5.0x6.4 mm and a thickness of 1.35 mm. The device operates within a supply voltage range of 3 V to 36 V and supports temperatures from -40°C to 105°C. Key electrical parameters include a typical channel current of 0.175 mA, input offset voltage maximum of 7 mV, and input/output voltage ranges extending to the negative rail.
Feature Summary
- Supports ground sense operation for single-supply applications
- Provides wide operating supply voltage range
- Features low power consumption per channel
Applications
- General-purpose analog signal processing
- Sensor interface circuits
- Industrial control systems
Procurement Notes
Verify the specific suffix E2 against official ROHM documentation to confirm RoHS compliance and material declarations. Confirm that the SSOP-B14 package matches the required footprint for PCB layout. Check the status as Not Recommended for New Designs (NRND) to ensure long-term availability aligns with product lifecycle requirements before finalizing procurement plans.
Selection Notes
Select this component when a quad operational amplifier with ground-sense capability is required. Ensure the design accommodates the 7 mV maximum input offset voltage and the specified slew rate limitations. Verify that the 36 V maximum supply voltage meets the system's power constraints and that the thermal performance remains within the -40°C to 105°C operating range under expected load conditions.
Part Context
This part belongs to the BA2902 series of ground sense operational amplifiers from ROHM Semiconductor. It is designed for applications requiring input signals near the negative supply rail. The device integrates four independent amplifiers in a compact surface-mount package, offering a balance between performance and power efficiency for general electronic equipment.
Replacement Considerations
Consult official ROHM substitution guides for verified alternatives. Cross-reference pinouts and electrical characteristics carefully if considering generic quad op-amps.
