LM393ADRG4

Overview

The LM393ADRG4 is a dual differential voltage comparator manufactured by Texas Instruments, belonging to the LM393A series. It features an open-collector output compatible with CMOS and TTL logic families. The device operates within a supply voltage range of 2 V to 36 V or ±1 V to ±18 V. Key electrical specifications include a maximum input offset voltage of 5 mV at 30 V, a typical quiescent current of 2.5 mA, and a propagation delay of 1.3 µs. It is housed in an 8-VSSOP package with a width of 3.00 mm and supports an operating temperature range from 0°C to +70°C.

Feature Summary

• Dual differential input configuration for precise voltage comparison
• Open-collector outputs enable wired-AND connections and level shifting
• Wide single-supply operation capability across low to high voltage ranges
• CMOS and TTL logic interface compatibility

Applications

• Overvoltage and undervoltage detection circuits
• Window comparator designs
• Threshold detection systems
• Level shifting applications

Procurement Notes

Verify the specific suffix 'RG4' confirms the RoHS-compliant tape-and-reel packaging variant. Confirm the 'A' grade designation aligns with required offset voltage tolerances. Ensure the 8-VSSOP footprint matches the target PCB layout constraints. Validate that the open-collector output architecture suits the downstream logic requirements without external pull-up resistors.

Selection Notes

Select this component when dual comparators are needed with wide supply voltage flexibility. The LM393ADRG4 offers a balance of speed and power consumption suitable for general-purpose analog switching. Consider the 5 mV max offset voltage if higher precision is required compared to standard LM393 variants. The VSSOP package is appropriate for space-constrained surface-mount designs.

Part Context

This part belongs to the Texas Instruments LMx93 family, which includes the LM193, LM293, and LM393. These devices are designed for single-supply operation with common-mode input voltages including ground. The LM393A series represents an improved version offering tighter electrical specifications than the standard LM393 while maintaining pin-out compatibility.
