TLV3494AIPWR

Comparators Overview

The TLV3494AIPWR is a quad nanopower push-pull output analog comparator manufactured by Texas Instruments. It operates within a supply voltage range of 1.8 V to 5.5 V and consumes only 1.2 uA of quiescent current per channel. The device features rail-to-rail inputs, allowing operation down to -200 mV below the negative rail. Key electrical specifications include a maximum input offset voltage of 15 mV, an input bias current of 10 pA, and a typical response time of 6 us. It is housed in a TSSOP-14 package and supports an operating temperature range from -40 C to +125 C.

Comparators Feature Summary

• Quad configuration with push-pull outputs for direct logic interfacing
• Nanopower consumption suitable for battery-operated applications
• Rail-to-rail input capability extending common-mode range below ground

Comparators Applications

• Battery-powered sensing systems requiring low standby current
• Threshold detection circuits in portable instrumentation
• Window comparator designs for voltage monitoring

Comparators Procurement Notes

Verify the specific suffix IPWR confirms the TSSOP-14 surface-mount package and reel packaging format. Ensure the design accounts for the humidity sensitivity classification during storage and reflow soldering processes. Confirm that the 1.2 uA quiescent current specification aligns with the system's power budget constraints under all operating conditions.

Comparators Selection Notes

Select this component when ultra-low power consumption is critical alongside the need for four independent comparison channels. The rail-to-rail input feature makes it suitable for single-supply applications where signals approach ground potential. Consider the 6 us response time against application speed requirements, as it is optimized for low power rather than high-speed switching.

Comparators Part Context

This part belongs to the TLV3494 family of general-purpose analog comparators. It shares core electrical characteristics with the TLV3494AID variant, differing primarily in the TSSOP-14 package versus SOIC-14. The series is designed for applications prioritizing minimal energy usage over high-frequency performance.
