Overview
The BA2904SFVM-TR is a dual-channel ground sense operational amplifier manufactured by ROHM Semiconductor. It operates on a single power supply ranging from 3 V to 32 V, with a maximum rating of 36 V. The device features a gain-bandwidth product of 500 kHz and a slew rate of 200 mV/µs. Input characteristics include a bias current of 20 nA and an offset voltage of 2 mV. Each channel provides an output current capability of 30 mA while consuming approximately 500 µA of supply current. It is housed in an 8-MSOP package and supports operation temperatures from -40°C to +105°C.
Feature Summary
- Supports ground sense input and output voltage ranges extending near the negative supply rail.
- Integrates internal phase compensation capacitors for stability without external components.
- Features low power consumption suitable for battery-operated applications.
Applications
- Single-supply signal conditioning circuits
- Low-power sensor interface designs
- General-purpose analog amplification
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required tape and reel packaging format. Check for RoHS compliance documentation relevant to your region's regulations. Ensure the operating temperature range aligns with your system's environmental requirements before finalizing procurement.
Selection Notes
Select this component when a dual op-amp with ground-referenced input/output capability is required under single-supply conditions. Consider the 500 kHz bandwidth and 200 mV/µs slew rate for moderate-speed applications. Evaluate the 8-MSOP package dimensions against available PCB space constraints. Compare input bias current specifications against other low-power alternatives if ultra-low leakage is critical.
Part Context
This part belongs to the BA2904S series of standard ground sense operational amplifiers. It shares functional similarities with the LM2904FVM-GTR but may differ in specific electrical parameters and automotive qualification status. The BA2904SF-E2 variant offers the same functionality in a SOP-8 package instead of MSOP-8.
Replacement Considerations
The LM2904FVM-GTR is listed as a substitute option by distributors. Verify pin compatibility and parameter alignment before replacement. Note that the BA2904SFVM-TR status is marked as Not Recommended for New Designs (NRND).
