BD12730G-GTR

Overview

The BD12730G-GTR is a single operational amplifier from ROHM Semiconductor, designed for low supply current applications. It operates within a voltage range of 1.8V to 5.5V and features rail-to-rail input and output capabilities. Key electrical parameters include a gain bandwidth product of 1 MHz, a slew rate of 0.4 V/µs, and an input bias current of 50 nA. The device exhibits a low equivalent input noise voltage of 10 nV/√Hz and a high phase margin of 75°. It is housed in a 5-pin SSOP package and is supplied in tape and reel format.

Feature Summary

• Operates with low supply voltage ranging from 1.8V to 5V
• Provides full swing input and output capability from ground to power supply level
• Features low equivalent input noise voltage for signal integrity
• Maintains high phase margin for stable operation

Applications

• Battery-powered devices requiring low current consumption
• Low-voltage signal processing circuits
• Portable electronic equipment

Procurement Notes

Verify the specific ordering suffix and package variant against the official ROHM datasheet to ensure compatibility with your design requirements. Confirm that the component meets RoHS standards if required by your manufacturing process. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.

Selection Notes

Select this component when a single-channel op amp with rail-to-rail I/O is needed for low-voltage systems. Consider its 1 MHz gain bandwidth and 0.4 V/µs slew rate for moderate-speed applications. Ensure the 5-pin SSOP package fits your PCB layout constraints. Evaluate the 50 nA input bias current and 10 nV/√Hz noise density against your signal chain requirements.

Part Context

The BD12730G-GTR belongs to the BD12730 series of operational amplifiers manufactured by ROHM Semiconductor. This series is characterized by low supply current and full-swing input/output performance. The GTR suffix indicates the tape and reel packaging format, distinguishing it from other packaging options like cut tape or tube variants within the same family.

Replacement Considerations

Check for pin-compatible alternatives such as the BD12732FV-GE2, noting differences in channel count and package type. Verify that any substitute maintains similar electrical characteristics, including supply voltage range and rail-to-rail capabilities, to ensure circuit functionality remains unchanged.
