BU7252F-E2

Comparators Overview

The BU7252F-E2 is a dual-channel analog comparator from ROHM Semiconductor, housed in an SOP-8 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 push-pull outputs capable of full-amplitude swing and draws a typical quiescent current of 35 µA. Key electrical specifications include a maximum input offset voltage of 11 mV, a typical input bias current of 0.001 nA, and a typical response time of 0.55 µs. It provides a typical output current of 6 mA and maintains high common-mode rejection and power supply rejection ratios of 80 dB.

Comparators Feature Summary

• Supports low-voltage operation with a wide supply range from 1.8 V to 5.5 V.
• Features push-pull outputs that allow for full-amplitude input and output voltage swings.
• Incorporates built-in electrostatic protection circuits rated at ±4000 V under the human body model.

Comparators Applications

• General-purpose signal comparison in low-voltage electronic circuits
• Threshold detection systems requiring fast response times
• Battery-powered devices due to low quiescent current consumption

Comparators Procurement Notes

Verify the specific suffix E2 against the manufacturer's latest datasheet to confirm package dimensions and tape-and-reel specifications. Ensure the procurement channel sources genuine ROHM products to avoid counterfeit components. Confirm RoHS compliance status directly with the supplier documentation prior to ordering.

Comparators Selection Notes

Select this component when a dual-channel comparator with push-pull outputs is required for low-voltage applications. It is suitable for designs needing full-swing output capabilities without additional level-shifting circuitry. Consider the 1.8 V minimum supply requirement and the 0.55 µs response time for timing-sensitive applications.

Comparators Part Context

This part belongs to the BU7252/BU7232 family of CMOS comparators. These integrated circuits are designed for monolithic integration of input full-amplitude push-pull output comparators. The series is characterized by low power consumption and very small input bias currents, making it distinct from higher-power operational amplifiers in the same product line.

Comparators Replacement Considerations
