BD5291G-GTL

Overview

The BD5291G-GTL is a single-channel operational amplifier manufactured by ROHM Semiconductor, housed in an SSOP-5 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 a maximum input offset voltage of 2.5 mV. The device operates with a typical supply current of 0.65 mA per channel and provides an output current of 17 mA. It supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Rail-to-rail input and output operation ensures wide dynamic range even at low supply voltages.
• MOSFET input stage provides extremely low input bias current for high-impedance applications.
• Low input offset voltage maintains signal accuracy in precision circuits.

Applications

• Sensor signal amplification
• Battery-powered portable devices
• Low-voltage analog signal processing

Procurement Notes

Verify the specific suffix (GTL) against the manufacturer's official documentation to confirm package type and availability status. Ensure the component meets RoHS compliance requirements for your region. Confirm that the intended application does not involve automotive use, as this series is generally not recommended for such environments. Cross-reference ordering numbers with authorized distributors to avoid counterfeit parts.

Selection Notes

Select this component when a single op-amp with rail-to-rail performance is required in a compact SSOP-5 package. It is suitable for designs needing low power consumption and operation down to 1.7V. Consider alternatives if higher bandwidth or automotive qualification is necessary. Verify that the 17mA output current meets load requirements.

Part Context

This part belongs to ROHM's low-voltage, low-power operational amplifier family. It shares core specifications with variants like the BD5291GWL-E2 but differs in packaging. The series is designed for general-purpose analog applications where space and power efficiency are critical constraints.

Replacement Considerations

The BD5291G-WTR is listed as a similar specification alternative with the same pinout and package. Verify compatibility before substitution.
