BU7252SFVM-TR

Comparators Overview

The BU7252SFVM-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 a push-pull output type. The device has a typical operating supply current of 35 uA and provides an output current of 6 mA per channel. Key electrical parameters include an input offset voltage of 11 mV, an input bias current of 1 pA, a common-mode rejection ratio of 80 dB, and a power supply rejection ratio of 80 dB. It is housed in an MSOP-8 package and supports surface mount installation.

Comparators Feature Summary

• Dual-channel general-purpose analog comparator with push-pull outputs
• Low power consumption suitable for battery-driven applications
• Wide single-supply voltage operation from 1.8 V to 5.5 V

Comparators Applications

• Battery-powered portable devices
• Sensor signal conditioning circuits
• General purpose voltage monitoring

Comparators Procurement Notes

Verify the specific suffix TR indicates tape and reel packaging configuration. Confirm the MSOP-8 package dimensions match the target PCB footprint requirements. Ensure the 1.8 V minimum supply voltage aligns with the system's power rail capabilities. Check that the 6 mA output drive capability meets the load requirements of the connected circuitry.

Comparators Selection Notes

Select this component when a low-power, dual-channel comparator is required for low-voltage systems. The MSOP-8 package offers a compact solution for space-constrained designs. The push-pull output simplifies interface design compared to open-collector alternatives. Verify that the 11 mV input offset voltage is acceptable for the application's precision needs.

Comparators Part Context

This part belongs to the BU7252 series of CMOS comparators from ROHM. The series is characterized by low voltage operation and low input bias current. The SFVM variant specifically denotes the MSOP-8 surface mount package. This family is designed for applications requiring efficient power usage in portable electronics.

Comparators Replacement Considerations

BU7252SF-E2 is a similar dual-channel comparator but uses an SOP-8 package instead of MSOP-8. Pinout compatibility should be verified before substitution due to potential package dimension differences.
