BA2901SFV-E2

Overview

The BA2901SFV-E2 is a general-purpose analog comparator manufactured by ROHM Semiconductor. It features four channels in an SSOP-B-14 surface-mount package. The device operates on a single power supply ranging from 2 V to 36 V or dual supplies of ±1 V to ±18 V. Key electrical specifications include a typical response time of 1.3 µs, a maximum input offset voltage of 7 mV, and a typical input bias current of 50 nA. Each channel provides an open-collector output capable of sourcing up to 16 mA. The component functions within a temperature range of -40°C to +105°C and consumes approximately 800 µA of quiescent current.

Feature Summary

• Supports wide single-supply operation from 2.0 V to 36.0 V
• Features standard open-collector outputs compatible with various logic families
• Includes built-in electrostatic protection circuits for enhanced reliability

Applications

• General-purpose signal comparison in industrial control systems
• Voltage monitoring and threshold detection circuits
• Oscillator and pulse generation applications

Procurement Notes

Verify the specific suffix and package variant against the official datasheet before procurement, as ordering codes may differ slightly across distributors. Confirm RoHS compliance status and check for any recent Product Change Notices (PCNs) regarding manufacturing location or material updates. Ensure the selected packaging format matches your assembly requirements, as reel and cut-tape options may have distinct handling specifications.

Selection Notes

Select this component when a low-cost, multi-channel comparator with ground-sense input capability is required. The open-collector output allows for flexible interfacing with different voltage levels via pull-up resistors. Consider the 1.3 µs response time for speed-sensitive designs and verify that the 16 mA sink current meets the load requirements. Evaluate thermal dissipation capabilities if operating near the upper temperature limits.

Part Context

This part belongs to the BA2901 series of analog comparators from ROHM Semiconductor. It is designed as a cost-effective solution for high-volume consumer and industrial electronics. The series typically offers pin-compatible alternatives with varying channel counts or package styles, allowing designers to scale functionality without changing the footprint significantly.

Replacement Considerations
