BD7561SG-TR

Overview

The BD7561SG-TR is a high-speed, single-channel operational amplifier manufactured by ROHM Semiconductor. It operates within a wide supply voltage range of +5.0 V to +14.5 V on a single supply or ±2.5 V to ±7.25 V on dual supplies. Key electrical parameters include a gain-bandwidth product of 1 MHz, a slew rate of 0.9 V/µs, and a typical quiescent current of 0.44 mA per channel. The device features input and output full-swing capabilities, with an input voltage range extending from VSS to VDD and an output swing of VSS+0.1 V to VDD-0.1 V. It is housed in an SSOP-5 package.

Feature Summary

• Supports high-voltage operation with a wide supply range up to 14.5 V single supply.
• Enables full-amplitude input and output signal swings for maximum dynamic range.
• Integrates internal phase compensation capacitors to ensure stability without external components.
• Features extremely low input bias current for high-impedance signal applications.

Applications

• General-purpose analog signal processing circuits
• Sensor interface amplification stages
• Industrial control system signal conditioning

Procurement Notes

Verify the specific suffix 'SG' against the manufacturer's official datasheet to confirm pinout and electrical specifications match your design requirements. Ensure the SSOP-5 package dimensions align with your PCB footprint. Confirm that the component status is listed as recommended for new designs rather than last-time buy or obsolete. Check RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component when a single-supply op amp requires high-voltage tolerance exceeding standard 5 V limits. The full-swing input/output characteristic makes it suitable for rail-to-rail applications where signal integrity near supply rails is critical. Consider the 1 MHz bandwidth and 0.9 V/µs slew rate for moderate-speed applications. Compare power consumption against lower-voltage alternatives if operating near the minimum supply threshold.

Part Context

This part belongs to the BD7561/BD7541 family of high-voltage CMOS operational amplifiers. The series integrates monolithic IC technology with built-in phase compensation. The 'SG' variant typically denotes specific packaging or thermal characteristics within the broader BD7561 product line, distinguished from the standard BD7561G by its specific mechanical or reliability attributes defined by ROHM.

Replacement Considerations

The BD7561G-TR is a direct functional substitute within the same family, sharing identical electrical specifications and pinouts. Verify that the replacement matches the SSOP-5 package dimensions and lead pitch. Ensure the substitute maintains the same high-voltage rating and full-sweep capabilities for circuit compatibility.
