BU7232SFVM-TR

Comparators Overview

The BU7232SFVM-TR is a low-power push-pull comparator manufactured by ROHM Semiconductor. It integrates two differential input circuits with full-amplitude push-pull outputs on a single chip. The device operates within a supply voltage range of +1.8V to +5.5V under single-supply conditions, or ±0.9V to ±2.75V under dual-supply conditions. Key electrical specifications include a maximum input offset voltage of 1mV, a typical input bias current of 0.001nA, and a typical response time of 1.7µs. It features a typical power supply rejection ratio (PSRR) of 80dB and operates over an extended temperature range from -40°C to +105°C.

Comparators Feature Summary

• Low power consumption with minimal operating current
• Full-amplitude push-pull output capability for direct interfacing
• Wide single and dual supply voltage operation
• Built-in electrostatic protection circuit

Comparators Applications

• Battery-powered portable devices requiring low quiescent current
• Threshold detection circuits in consumer electronics
• Signal conditioning in low-voltage analog systems

Comparators Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected package variant matches the PCB footprint requirements. Cross-reference the exact part number with authorized distributors to avoid counterfeit components.

Comparators Selection Notes

Select this component for designs requiring dual comparators in a compact MSOP8 package. It is suitable for applications where low input bias current and wide common-mode voltage range are critical. Consider the 1.7µs response time for speed-sensitive signal processing tasks. Evaluate the 1mV max offset voltage against system accuracy requirements.

Comparators Part Context

This part belongs to the BU7232SF family of CMOS comparators designed for low-voltage operations. It shares architectural similarities with the BU7252 series but offers optimized performance for general-purpose low-power applications. The device is distinct from voltage detectors like the BU4232 series, focusing instead on high-speed differential comparison rather than reset generation.
