BA2902YF-LBH2

Overview

The BA2902YF-LBH2 is a ground sense operational amplifier manufactured by ROHM Semiconductor. It features four channels within an SOP14 package, supporting a wide operating supply voltage range from 3V to 36V. The device operates reliably across an extended temperature range of -40°C to 125°C. Key electrical characteristics include a typical circuit current of 0.8mA per channel, a maximum input offset voltage of 7mV, and a typical input bias current of 50nA. It offers a typical response time of 1.3µs and a voltage gain of 100dB.

Feature Summary

• Ground sense capability allowing common-mode input voltage range to include ground level
• Support for single or dual power supply operation with wide operating supply voltage
• Standard comparator pin-assignments for simplified integration
• Extended temperature range suitable for industrial applications

Applications

• Industrial equipment requiring long-term product support
• Systems utilizing standard comparator pin-assignments
• Applications needing ground-level signal sensing

Procurement Notes

Verify the specific suffix (LBH2) against official documentation to confirm package type and tape-and-reel specifications. Confirm that the NRND status aligns with your project's lifecycle requirements, as this component is intended for existing customers rather than new designs. Ensure compatibility with SOP14 footprint constraints during procurement planning.

Selection Notes

Select this component when ground-sense input capability is required alongside standard comparator pinouts. It is suitable for designs needing wide supply voltage flexibility and industrial-grade temperature stability. Consider its NRND status carefully; it is appropriate for maintaining existing systems but may not be ideal for new long-term development projects seeking actively promoted alternatives.

Part Context

This part belongs to ROHM's series of ground sense operational amplifiers designed for industrial markets. It provides a solution for applications where signals near ground potential must be accurately processed. The device integrates multiple channels in a compact surface-mount package, balancing performance with space efficiency for various control and sensing tasks.

Replacement Considerations

Check for updated equivalents within the same family if new design availability is critical. Verify pinout compatibility before substituting with other ground-sense amplifiers.
