TLV3491AIDR

Comparators Overview

The TLV3491AIDR is a single-channel, general-purpose analog comparator manufactured by Texas Instruments. It operates within a supply voltage range of 1.8 V to 5.5 V and features rail-to-rail input capability with CMOS push-pull output. Key electrical specifications include a maximum quiescent current of 1.2 µA, an input bias current of 10 pA at 5.5 V, and a maximum input offset voltage of 15 mV at 5.5 V. The device exhibits a typical common-mode rejection ratio (CMRR) of 74 dB and a power supply rejection ratio (PSRR) of 69.12 dB. Propagation delay is specified at a maximum of 13.5 µs. It functions reliably across an industrial temperature range of -40°C to +125°C.

Comparators Feature Summary

• Nanopower consumption with low quiescent current for battery-operated applications
• Rail-to-rail input stage allowing full signal swing utilization
• CMOS push-pull output providing full-swing logic compatibility

Comparators Applications

• Battery-powered sensor interfaces
• Threshold detection circuits
• Low-power monitoring systems

Comparators Procurement Notes

Verify the specific suffix 'DR' indicates tape-and-reel packaging when sourcing. Confirm the operating temperature grade matches design requirements. Ensure ESD handling protocols are followed during assembly. Cross-reference the manufacturer part number against official datasheets to validate revision levels before integration into production.

Comparators Selection Notes

Select this component for designs requiring minimal static power draw while maintaining standard comparator functionality. The rail-to-rail inputs simplify interface design with various sensors. Verify that the propagation delay meets timing constraints, as it is relatively slow compared to high-speed comparators. Ensure the supply voltage remains within the 1.8 V to 5.5 V window for optimal performance.

Comparators Part Context

This device belongs to the TLV349x family of nanopower comparators from Texas Instruments. It shares core architectural similarities with other members like the TLV3491AIDBVT but differs in package type and reel configuration. The family is designed for cost-sensitive, low-power applications where precise high-speed switching is not the primary requirement.

Comparators Replacement Considerations

Direct pin-compatible alternatives within the same family include the TLV3491AIDBVT. Other nanopower comparators may require circuit adjustments due to differing pinouts or electrical characteristics.
