BD7561G-TR

Overview

The BD7561G-TR is a single-channel high-speed operational amplifier manufactured by ROHM Semiconductor. It operates within a supply voltage range of 5 V to 14.5 V, supporting dual supplies from ±2.5 V to ±7.25 V. Key electrical specifications include a gain-bandwidth product of 1 MHz and a slew rate of 900 mV/µs. The device draws a typical operating current of 440 µA per channel and provides an output current capability of 8 mA. It features a low input offset voltage of 1 mV and an input bias current of 1 pA. The component is housed in an SSOP-5 surface-mount package and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Supports full input and output voltage swing capabilities
• Features extremely low input bias current for precision applications
• Includes built-in phase compensation capacitors

Applications

• High-speed signal processing circuits
• Industrial control systems requiring wide voltage operation
• Portable battery-powered equipment due to low power consumption

Procurement Notes

Verify the specific suffix 'G-TR' corresponds to the SSOP-5 package and taping reel configuration as listed in official ROHM documentation. Confirm that the RoHS compliance status matches current regulatory requirements for your target market. Ensure the operating temperature range of -40°C to +85°C aligns with your environmental design constraints before finalizing procurement.

Selection Notes

Select this component when a single-channel amplifier requires high-speed performance with a 1 MHz bandwidth and 900 mV/µs slew rate. It is suitable for designs needing a wide single-supply voltage range up to 14.5 V while maintaining low quiescent current. Consider this part over lower-speed variants if faster transient response is necessary for the application.

Part Context

This device belongs to the BD7561/BD7541 family of high-voltage CMOS operational amplifiers. These monolithic ICs integrate input-output full-swing amplifiers with internal phase compensation. The family is characterized by wide operating voltage ranges and minimal input bias currents, designed for efficient performance in various electronic systems.

Replacement Considerations

The BD7561SG is a verified substitute within the same series offering identical electrical characteristics but with an extended maximum operating temperature of 105°C compared to the standard 85°C rating.
