Overview
The BA10393 is a dual comparator integrated circuit manufactured by Rohm Semiconductor. It features open-collector outputs suitable for wired OR connections. The device operates on a single power supply ranging from 2V to 36V, or a dual supply of ±1V to ±18V. Key electrical characteristics include a typical quiescent current of 0.4mA at 5V, an input offset voltage typically of ±1.0mV, and a response time of 1.3ms. The component supports an operating temperature range of -40°C to +85°C.
Feature Summary
- Dual comparators with open-collector output enabling wired OR connections
- Wide operating voltage range supporting single and dual power supplies
- Low current dissipation and low input offset voltage
- Wide common-mode input voltage capability
Applications
- Temperature sensor circuits
- Pressure sensor interfaces
- Current sensor monitoring systems
Procurement Notes
Verify the specific package variant required for the design, as the BA10393 family includes DIP-8 (BA10393), SOP-8 (BA10393F), and SIP-8 (BA10393N). Confirm that the selected part matches the intended mounting style and thermal dissipation requirements. Ensure compatibility with existing 393-series comparator designs if cross-referencing specifications.
Selection Notes
Select this component for applications requiring ground-sense comparators with wide common-mode input voltage ranges extending down to 0V. The open-collector output allows flexibility in interfacing with different logic levels through external pull-up resistors. Consider the low quiescent current for battery-powered or energy-efficient system designs.
Part Context
The BA10393 belongs to a series of dual comparators designed for general-purpose electronic equipment. It is compatible with standard 393 comparators from other manufacturers, facilitating direct replacement in many existing designs. The series includes variations tailored for through-hole and surface-mount technologies.

FAQ
What is the maximum differential input voltage?
The absolute maximum differential input voltage is equal to the power supply voltage (VCC).
How should unused comparator circuits be handled?
It is recommended to connect the input of unused circuits to a potential within the in-phase input voltage range (VICM) and leave the output open.
