BU7233SF-E2

Comparators Overview

The BU7233SF-E2 is a dual-channel analog comparator manufactured by ROHM Semiconductor, housed in an SOP-8 surface-mount package. It operates within a supply voltage range of 1.8 V to 5.5 V and draws a typical operating current of 10 µA. The device features open-drain outputs capable of sourcing 6 mA per channel. Key electrical specifications include a maximum input offset voltage of 11 mV, a typical response time of 1.8 µs, and a voltage gain of 90 dB. It supports full-swing input voltage ranges from VSS to VDD and maintains functionality across an extended temperature range of -40°C to +105°C.

Comparators Feature Summary

• Low power consumption with minimal operating current suitable for battery-driven applications
• Full-swing input capability allowing signal detection across the entire supply rail
• Open-drain output configuration providing flexible interfacing options
• Extended operational temperature range for reliable performance in varied environments

Comparators Applications

• Battery-powered portable electronic devices requiring low standby current
• General-purpose signal comparison circuits in consumer electronics
• Threshold detection systems in industrial control equipment
• Voltage monitoring applications in low-voltage digital logic interfaces

Comparators Procurement Notes

Verify the specific suffix E2 against the manufacturer's latest documentation to confirm compliance with current environmental standards and pinout configurations. Ensure that the SOP-8 package dimensions match the target PCB footprint requirements. Confirm that the open-drain output architecture aligns with the pull-up resistor requirements of the downstream circuitry. Validate that the operating temperature range meets the specific environmental conditions of the intended deployment scenario.

Comparators Selection Notes

Select this component when a dual-channel comparator with ultra-low quiescent current is required for low-voltage systems. The open-drain output necessitates external pull-up resistors, which must be sized appropriately for the desired switching speed and load. Consider the 11 mV maximum input offset voltage when designing high-precision threshold detection circuits. The wide input voltage range simplifies interface design by eliminating the need for level shifting in many single-supply applications.

Comparators Part Context

The BU7233SF-E2 belongs to ROHM's series of low-power analog comparators designed for general-purpose applications. It shares functional similarities with other members of the BU723x family but offers specific packaging and environmental ratings. The device is positioned as a standard-grade component suitable for non-automotive consumer electronics. Its design emphasizes energy efficiency and compact form factor integration for modern portable devices.

Comparators Replacement Considerations

Consult official substitution guides for compatible alternatives such as the BU7233YF-CGE2, ensuring pin compatibility and electrical parameter alignment. Verify that any substitute part maintains the same open-drain output structure and supply voltage range. Cross-reference thermal characteristics and package dimensions to ensure mechanical fit without redesigning the printed circuit board layout.
