BU7232FVM-TR

Comparators Overview

The BU7232FVM-TR is a CMOS low-voltage push-pull comparator from ROHM Semiconductor, featuring two independent circuits in an 8-MSOP package. It operates on a single supply voltage ranging from +1.8V to +5.5V, or dual supplies of ±0.9V to ±2.75V. Key electrical parameters include a typical supply current of 0.01mA per channel, a maximum input offset voltage of 11mV, and a typical input bias current of 0.001nA. The device exhibits a typical response time of 1.7µs, a voltage gain of 90dB, and an output current capability of 6mA. It supports full-amplitude input and output swings and includes built-in electrostatic protection with a typical Human Body Model rating of ±4000V. The operating temperature range spans from -40°C to +85°C.

Comparators Feature Summary

• Low power consumption with minimal supply current draw suitable for battery-operated applications
• Full-amplitude input and output voltage swing capabilities across the entire supply range
• Push-pull output structure providing strong drive capability without external pull-up resistors
• Integrated electrostatic discharge protection circuitry for enhanced reliability

Comparators Applications

• Battery-powered portable electronic devices requiring low quiescent current
• Threshold detection circuits in consumer electronics
• Signal conditioning interfaces for microcontrollers
• Level shifting applications in low-voltage logic systems

Comparators Procurement Notes

Verify the specific ordering suffix matches the required tape-and-reel quantity of 3000 units. Confirm that the MSOP8 package dimensions align with your PCB footprint requirements. Ensure compliance with RoHS directives if applicable to your manufacturing standards. Check for any regional export control classifications such as EAR99 before finalizing procurement. Validate that the component status remains active for long-term production needs.

Comparators Selection Notes

Select this component when low voltage operation below 3.3V is required alongside high input impedance characteristics. The push-pull output eliminates the need for external pull-up components, simplifying board design. Consider the 11mV maximum input offset voltage for precision threshold applications. Evaluate the 1.7µs response time against signal frequency requirements to ensure adequate speed for the intended application.

Comparators Part Context

This part belongs to the BU7232/BU7252 family of monolithic CMOS comparators designed for low-voltage efficiency. It integrates two comparator circuits on a single chip, offering a compact solution compared to discrete implementations. The series emphasizes low power consumption and wide input voltage ranges, making it distinct from standard rail-to-rail operational amplifiers used in similar roles.
