BU7252FVM-TR

Comparators Overview

The BU7252FVM-TR is a dual-channel analog comparator manufactured by ROHM Semiconductor. It operates within a supply voltage range of 1.8 V to 5.5 V and features push-pull outputs capable of sourcing or sinking up to 6 mA per channel. The device exhibits low power consumption with an operating current of 35 µA, alongside high input impedance characterized by a bias current of 1 pA. Input offset voltage is specified at 11 mV maximum, while common-mode rejection ratio and power supply rejection ratio are both rated at 80 dB. It is housed in an MSOP-8 surface-mount package.

Comparators Feature Summary

• Dual-channel general-purpose analog comparator architecture
• Push-pull output stage for full amplitude operation
• Ultra-low input bias current capability
• Wide single-supply voltage compatibility

Comparators Applications

• General purpose signal comparison circuits
• Low voltage portable electronic devices
• Battery-powered sensor interfaces
• Threshold detection systems

Comparators Procurement Notes

Verify the specific suffix TR indicates tape and reel packaging configuration when ordering. Confirm the MSOP-8 footprint matches the target PCB layout dimensions. Ensure supply voltage constraints between 1.8 V and 5.5 V align with system requirements. Check RoHS compliance documentation for regulatory adherence. Validate thermal performance within the -40°C to +85°C operating range.

Comparators Selection Notes

Select this component for applications requiring low power dissipation and rail-to-rail output swing without external pull-up resistors. The push-pull output simplifies interface design compared to open-collector alternatives. Consider the 11 mV offset voltage limit for precision threshold applications. The 35 µA quiescent current makes it suitable for battery-operated equipment where energy efficiency is critical.

Comparators Part Context

This part belongs to the BU7252F series of CMOS comparators from ROHM Semiconductor. The family includes variants with different packaging options such as SOP-8 and MSOP-8. The FVM suffix specifically denotes the MSOP-8 package type with tape and reel delivery. These devices are designed for low-voltage digital and analog mixed-signal systems.

Comparators Replacement Considerations

BU7252F-E2 is a pin-compatible alternative in SOP-8 packaging. Verify electrical parameter equivalence before substitution. Package dimensions differ between MSOP-8 and SOP-8 formats.
