BD5291FVE-GTR

Overview

The BD5291FVE-GTR is a single-channel operational amplifier manufactured by ROHM Semiconductor, housed in a VSOF5 package. It features rail-to-rail input and output capabilities with a supply voltage range of 1.7V to 5.5V. Key electrical parameters include a gain-bandwidth product of 3.2 MHz, a slew rate of 2.5 V/µs, and an input offset voltage maximum of 2.5 mV. The device operates with a typical circuit current of 0.65 mA per channel and provides an output current of 17 mA. It offers high voltage gain (110 dB), low input bias current (0.001 nA), and a common-mode rejection ratio of 90 dB. The component functions within a temperature range of -40°C to +85°C.

Feature Summary

• Rail-to-rail input and output operation ensures wide signal range even at low supply voltages.
• MOSFET input stage provides extremely low input bias current suitable for precision applications.
• High voltage gain and low input offset voltage support accurate signal amplification.

Applications

• Sensor amplifier circuits requiring low bias current
• Low-voltage analog signal processing systems
• Portable electronic devices powered by single supplies

Procurement Notes

Verify the specific suffix GTR indicates tape-and-reel packaging configuration. Confirm RoHS compliance status through official documentation. Ensure the VSOF5 package dimensions match PCB footprint requirements. Check for any design-in restrictions or obsolescence notices from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when rail-to-rail performance is required with a minimum supply voltage of 1.7V. The low input bias current makes it suitable for high-impedance sensor interfaces. Compare the 3.2 MHz bandwidth against application speed requirements. Verify that the VSOF5 package size fits the available board space constraints.

Part Context

This part belongs to the BD5291 series of single operational amplifiers. It shares core electrical characteristics with variants like BD5291GWL and BD5291FVE but differs in packaging. The FVE variant utilizes the VSOF5 package, while other versions may use WLCSP or SSOP formats. All variants maintain the same fundamental low-voltage, rail-to-rail specifications.

Replacement Considerations

BD5291GWL-E2: Different WLCSP-5 package; verify pinout compatibility. BD5291FVE: Same electrical specs but different reel quantity; check packaging requirements. BD5291G: Different SSOP5 package; ensure mechanical fit.
