TLV3701IDR

Comparators Overview

The TLV3701IDR is a single-channel nanopower analog comparator from Texas Instruments, housed in an 8-pin SOIC package. It operates on a supply voltage range of 2.7 V to 16 V with a typical supply current of 560 nA per channel. The device features a push-pull CMOS output stage and supports an input common-mode range extending from –0.1 V to VCC + 5 V. Key electrical specifications include a maximum input offset voltage of 5 mV at 25°C and a propagation delay of approximately 34 µs to 45 µs depending on overdrive conditions. It functions reliably within an industrial temperature range of –40°C to +125°C.

Comparators Feature Summary

• Ultra-low power consumption suitable for battery-powered applications
• Extended input common-mode range exceeding the positive supply rail
• Integrated Power-on-Reset circuitry for defined startup states
• Fail-safe inputs maintaining high impedance during power-down

Comparators Applications

• Portable battery monitoring systems
• Consumer medical electronics
• Security detection systems
• Handheld instruments
• Ultra-low power wireless devices

Comparators Procurement Notes

Verify that the ordering suffix 'R' corresponds to the taped-and-reeled packaging format specified in the datasheet. Confirm the 'I' suffix indicates the industrial temperature grade (-40°C to +125°C) rather than the commercial grade. Ensure the SOIC-8 package matches the required footprint for the design. Cross-reference the specific revision level of the datasheet SLCS137D or later for any updates to electrical characteristics or mechanical dimensions before finalizing procurement.

Comparators Selection Notes

Select this component when low quiescent current is critical for system longevity. The push-pull output eliminates the need for external pull-up resistors, simplifying circuit design compared to open-drain alternatives. The wide input common-mode range allows operation with signals exceeding the supply voltage, which is advantageous in single-supply applications. Consider the thermal resistance values provided in the datasheet if operating near the upper limits of the temperature range or under high load conditions.

Comparators Part Context

This part belongs to the TLV370x family of nanopower comparators, which also includes dual (TLV3702) and quad (TLV3704) variants. The family shares similar electrical characteristics but differs in channel count and package options. The TLV3701IDR specifically denotes the single-channel version in the SOIC-8 package with industrial temperature rating. Other packages for the TLV3701 include SOT-23-5 and PDIP-8.

Comparators Replacement Considerations

Direct pin-compatible replacements within the same family include TLV3701CDR (commercial grade) or TLV3701IDBV (SOT-23 package). For different package requirements, verify pinout compatibility with other SOIC-8 comparers such as the TLC3701, noting differences in supply current and speed.
