The CSDA1BA is a Digital Current Sensor, provides a logic level output that changes from approximately Vcc to 0.4V when the sensed current exceeds the operate point. Each digital sensor will operate on ac or dc current, but the output will turn off at every zero crossing when sensing AC current.

• Digital output
• AC or DC current sensing
• Through-hole design
• Output voltage isolation from input
• Minimum energy dissipation
• Maximum current limited only by conductor size
• Accurate, low cost sensing
• -25 to 85°C operating temperature range
