BU7233F-E2

Comparators Overview

The BU7233F-E2 is a dual-channel analog comparator manufactured by ROHM Semiconductor, housed in an 8-SOP surface-mount package. It operates on a single supply voltage ranging from 1.8 V to 5.5 V or dual supplies of ±0.9 V to ±2.75 V. The device features an open-drain output capable of sourcing 6 mA per channel and draws a typical operating current of 10 µA. Key electrical specifications include a maximum input offset voltage of 11 mV, a typical input bias current of 1 pA, and a propagation delay of 1.8 µs. Common-mode rejection ratio and power supply rejection ratio are both specified at 80 dB. The component functions within a temperature range of -40°C to +85°C.

Comparators Feature Summary

• Supports low-voltage operation with a wide supply range from 1.8 V to 5.5 V.
• Features ultra-low input bias current for minimal signal loading.
• Provides open-drain output configuration for flexible interfacing.

Comparators Applications

• Battery-powered portable devices requiring low quiescent current
• Threshold detection circuits in consumer electronics
• Signal conditioning stages in sensor interfaces

Comparators Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging and tape-and-reel specifications. Confirm that the 8-SOP package dimensions align with your PCB footprint requirements. Check RoHS compliance status and moisture sensitivity level before integration into production workflows. Ensure supply chain sources provide authentic components with traceable documentation.

Comparators Selection Notes

Select this component when designing circuits that require low power consumption and high input impedance. The open-drain output necessitates an external pull-up resistor; verify the target logic voltage levels during design. Consider the 1.8 µs propagation delay for timing-critical applications. The wide common-mode input range extending to the supply rails simplifies interface design with various signal sources.

Comparators Part Context

This part belongs to the BU7233 series of low-power CMOS comparators from ROHM Semiconductor. It is designed for general-purpose comparison tasks where energy efficiency is prioritized over speed. The device integrates two independent comparators into a compact SOP-8 package, making it suitable for space-constrained designs in portable and battery-operated equipment.

Comparators Replacement Considerations

Consult the official ROHM replacement guide for verified cross-reference part numbers. Ensure any substitute maintains compatible pinout, supply voltage range, and output configuration. Verify thermal performance and package dimensions match the existing design constraints before implementation.
