TLV3492AIDR

Comparators Overview

The TLV3492AIDR is a dual nanopower 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 consumes only 1.2 uA of quiescent current per channel. The device features rail-to-rail inputs and push-pull outputs, with a typical response time of 6 us. Key electrical specifications include a maximum input offset voltage of 15 mV, input bias current of 10 pA, and a common-mode rejection ratio of 54 dB. It supports operation from -40 C to +125 C.

Comparators Feature Summary

• Dual-channel configuration with nanopower consumption for extended battery life
• Rail-to-rail input capability allowing full signal swing utilization
• Push-pull output stage providing direct logic interface compatibility

Comparators Applications

• Battery-powered sensor monitoring systems
• Threshold detection circuits in low-power instrumentation
• General-purpose voltage comparison in portable devices

Comparators Procurement Notes

Verify the specific ordering suffix 'IDR' corresponds to the SOIC-8 tape-and-reel packaging format required for automated assembly processes. Confirm that the component meets RoHS compliance standards applicable to your manufacturing region. Ensure thermal management considerations align with the SOIC-8 package power dissipation limits under maximum operating temperature conditions.

Comparators Selection Notes

Select this component when ultra-low static current is critical compared to standard comparators. The dual-channel architecture reduces board space relative to single-channel alternatives. Verify that the 6 us propagation delay meets system timing requirements, as faster options like the TLV3501 exist for high-speed applications.

Comparators Part Context

This part belongs to the TLV349x family of nanopower comparators designed for energy-efficient applications. It shares architectural similarities with the single-channel TLV3491 but provides two independent comparison functions in one package. The series emphasizes low power consumption while maintaining adequate speed for general-purpose tasks.

Comparators Replacement Considerations

The TLV3491AID serves as a single-channel equivalent within the same family. For higher speed requirements, the TLV3501AIDR offers nanosecond response times but at significantly higher current consumption.
