BU7462FVM-TR

Overview

The BU7462FVM-TR is a dual-channel CMOS operational amplifier manufactured by Rohm Semiconductor. It operates within a supply voltage range of 1.7 V to 5.5 V, consuming only 300 µA of supply current per channel. The device features a gain-bandwidth product of 1 MHz and a slew rate of 1 V/µs. Key electrical specifications include an input offset voltage of 1 mV, input bias current of 1 pA, and output current capability of 12 mA. It supports ground-sense input and full-swing output in an 8-MSOP package.

Feature Summary

• CMOS technology enabling low power consumption with 300 µA supply current
• Ground-sense input capability allowing operation down to the negative rail
• Full-swing output design maximizing dynamic range at low voltages
• Single-chip integration with internal phase compensation capacitors

Applications

• Battery-powered portable electronic devices requiring low quiescent current
• Signal conditioning circuits for sensors operating near ground potential
• Low-voltage analog signal processing in consumer electronics
• Interface circuits for microcontrollers with single-supply operation

Procurement Notes

Verify the specific ordering code BU7462FVM-TR against the manufacturer's latest documentation to ensure correct packaging and tape-and-reel configuration. Confirm that the 8-MSOP package dimensions align with your PCB footprint requirements. Check for any recent updates to the RoHS compliance status or environmental declarations directly from Rohm Semiconductor before finalizing procurement.

Selection Notes

Select this component when a dual-channel op amp is required with ground-sense input and full-swing output capabilities under low voltage conditions. It is suitable for applications needing 1 MHz bandwidth and 1 V/µs slew rate with minimal power draw. Compare against the BU7442FVM-TR if lower current consumption is prioritized over speed, or the BU7461SFVM-TR for single-channel variants.
