Overview

The BA10393F-E2 is a high-gain, dual independent comparator from Rohm Semiconductor designed for general-purpose applications. It features a wide operating voltage range from 2V to 36V and utilizes an open-collector output, allowing for easy level-shifting and wired-OR logic configurations.

Why Choose This Part

The device offers excellent versatility with a common-mode input voltage range that includes ground, even when operating from a single supply. Its low typical quiescent current of 0.4mA and small SOP8 footprint make it suitable for space-constrained and power-sensitive designs.

Applications

Limit Comparators
Used in threshold detection circuits to monitor sensor outputs against a fixed reference voltage.
Level Translators
Utilizes the open-collector output to interface between different logic voltage levels up to 36V.
Square Wave Oscillators
Combined with RC networks to generate clock pulses or timing signals in low-frequency systems.
Battery Voltage Monitoring
Detects low-battery conditions in portable electronics due to its low 0.4mA typical supply current.

Getting Started

Ensure a pull-up resistor is connected to the open-collector output to define the high-level logic voltage. When prototyping, place a 0.1uF ceramic bypass capacitor close to the VCC pin to minimize switching noise in sensitive threshold applications.
