TLV3702CDGKG4

Comparators Overview

The TLV3702CDGKG4 is a dual nanopower comparator from Texas Instruments featuring push-pull CMOS outputs. It operates on a single supply voltage ranging from 2.5V to 16V, with an extended industrial temperature range of -40°C to +125°C for the I-suffix variant. The device draws only 560nA per channel at 25°C. Key electrical specifications include a maximum input offset voltage of 5mV and an input common-mode range extending from -0.1V to VCC + 5V. Propagation delays are typically 34µs (low-to-high) and 45µs (high-to-low). It is housed in an 8-pin VSSOP package.

Comparators Feature Summary

• Ultra-low power consumption with 560nA per channel supply current
• Input common-mode range exceeds supply rails by up to 5V
• Integrated Power-on-Reset circuitry for stable startup
• Fail-safe inputs maintaining high impedance independent of supply voltage

Comparators Applications

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

Comparators Procurement Notes

Verify the specific suffix 'I' or 'C' to confirm the operating temperature range, as the base model number does not explicitly define thermal limits in the provided text. Confirm the DGKG4 suffix corresponds to the VSSOP-8 package type. Ensure design compatibility with the specified 2.5V minimum supply voltage for the intended application environment.

Comparators Selection Notes

Select this component when minimizing quiescent current is critical compared to speed requirements. The TLV3702 offers rail-to-rail input capability exceeding the positive supply, unlike standard comparators. Consider the propagation delay characteristics if fast switching is required, as it is slower than general-purpose alternatives like the TLC3702 family.

Comparators Part Context

This device belongs to the TLV370x family of nanopower comparators, which includes single (TLV3701), dual (TLV3702), and quad (TLV3704) configurations. The family is designed specifically for battery-powered applications where low current draw is the primary design constraint. It serves as a low-power alternative to higher-current comparators while providing robust input protection features.

Comparators Replacement Considerations

The TLC3702 is a functional replacement offering faster propagation speeds but significantly higher supply current. For automotive applications, the TLV3702QDRG4Q1 provides AEC-Q100 qualification.
