BU7232YFVM-CTR

Comparators Overview

The BU7232YFVM-CTR is a dual-channel analog comparator manufactured by Rohm Semiconductor, housed in an 8-MSOP surface-mount package. It operates on a single supply voltage ranging from 1.8V to 5.5V, or dual supplies of ±0.9V to ±2.75V. The device features push-pull outputs capable of delivering up to 7mA per channel and draws a maximum static current of 25µA. Key electrical specifications include a propagation delay of 1.7µs, an input offset voltage of 14mV at 3V, and an input bias current of 1pA at 3V. Common-mode rejection ratio and power supply rejection ratio are typically 80dB. It functions within a temperature range of -40°C to 125°C.

• General-purpose threshold detection
• Level shifting interfaces

Comparators Procurement Notes

Verify the specific suffix 'CTR' indicates tape-and-reel packaging when sourcing components. Confirm RoHS compliance status matches current regulatory requirements for your region. Ensure the 8-MSOP footprint aligns with your PCB design constraints. Check for any automotive qualification requirements if deploying in vehicle environments, as this standard grade part may not be suitable for all automotive safety analyses.

Comparators Selection Notes

Select this component when a dual comparator with low power consumption and wide supply voltage flexibility is required. The push-pull output eliminates the need for external pull-up resistors, simplifying circuit design. Consider the 1.7µs response time for applications requiring moderate speed. Verify that the 14mV input offset voltage meets the precision requirements of your specific application compared to higher-precision alternatives.

Comparators Part Context

This part belongs to the BU7232 series of low-power CMOS comparators from Rohm Semiconductor. It is designed for general-purpose use in consumer electronics and industrial applications where low voltage operation is critical. The MSOP8 package provides a compact solution for space-constrained designs. It is distinct from the BA series which often targets automotive grades with wider supply ranges.

Comparators Replacement Considerations

The BU7232SFVM is a similar dual-channel comparator in the same family but has different thermal characteristics and potentially different offset voltage specifications. Verify pin compatibility and electrical parameters before substitution. No other direct cross-reference parts are confirmed in the provided documentation.
