TLV3491AIDG4

Comparators Overview

The TLV3491AIDG4 is a single-channel analog comparator manufactured by Texas Instruments, housed in an SOIC-8 surface-mount package. It operates within a supply voltage range of 1.8 V to 5.5 V and features rail-to-rail input capability with a push-pull output configuration. The device exhibits a maximum propagation delay of 6 µs and a typical common-mode rejection ratio of 54 dB. It draws a maximum operating supply current of 1.2 µA and supports an extended industrial temperature range from -40°C to +125°C.

Comparators Feature Summary

• Rail-to-rail input stage enables operation across the full supply voltage range
• Push-pull output structure provides robust signal driving capability
• Ultra-low quiescent current consumption supports battery-powered applications
• Integrated thermal protection safeguards against overheating conditions

Comparators Applications

• Battery-operated sensing systems requiring minimal power draw
• Threshold detection circuits in portable instrumentation
• Voltage monitoring in low-power embedded controllers
• Signal conditioning for microcontroller input interfaces

Comparators Procurement Notes

Verify the specific suffix G4 indicates lead-free compliance and RoHS status before procurement. Confirm the SOIC-8 package variant matches the target PCB footprint. Ensure the operating temperature range aligns with the intended environmental conditions. Cross-reference the datasheet revision to confirm electrical characteristics match the design requirements.

Comparators Selection Notes

Select this component when ultra-low static current is critical compared to standard comparators. The rail-to-rail input allows direct interfacing with sensors without level shifting. Consider the 6 µs propagation delay for timing-sensitive applications. Evaluate the push-pull output against open-drain alternatives based on pull-up resistor requirements.
