TLV1842QDGKRQ1

Comparators Overview

The TLV1842QDGKRQ1 is an automotive-grade, dual high-speed comparator from Texas Instruments. It operates within a wide supply voltage range of 2.7 V to 40 V and features open-drain outputs. The device offers a propagation delay of 10 ns and a slew rate of 35 V/µs. Input characteristics include a maximum input offset voltage of 5 mV and low input bias current. It supports rail-to-rail input operation and functions reliably across an extended temperature range from -40°C to +125°C.

Comparators Feature Summary

• Automotive qualification supporting AEC-Q100 standards for reliability in vehicle environments
• High-voltage capability with a supply range extending up to 40 V
• Open-drain output configuration allowing flexible interfacing with various logic levels

Comparators Applications

• Automotive sensor signal conditioning
• High-voltage battery management systems
• Industrial process control monitoring

Comparators Procurement Notes

Verify the specific suffix DGKR indicates the VSSOP-8 package and reel packaging format. Confirm the Q1 designation aligns with required automotive quality standards. Ensure the operating environment matches the specified temperature range. Validate that the open-drain output topology suits the downstream circuit requirements without additional pull-up components.

Comparators Selection Notes

Select this component when high-voltage tolerance and fast switching are critical. The open-drain output requires external pull-up resistors, which must be sized for the desired speed and voltage level. Consider the 5 mV offset voltage for precision applications. Compare against standard comparators if automotive certification is not mandatory.

Comparators Part Context

This part belongs to the TLV184x-Q1 family of high-speed comparators. It shares architectural similarities with other members but is distinguished by its dual-channel configuration and specific automotive grading. The family targets applications requiring robust performance under harsh electrical conditions.

Comparators Replacement Considerations

Check for direct pin-compatible alternatives within the TLV18xx-Q1 series. Verify that substitute parts maintain the 40 V maximum rating and 10 ns propagation delay. Ensure the replacement also meets automotive reliability requirements.
