TLV9024DR

Comparators Overview

The TLV9024DR is a quad-channel precision analog comparator from Texas Instruments, housed in a 14-pin SOIC package. It operates on a supply voltage range of 1.65V to 5.5V with a typical quiescent current of 17.1µA per channel. The device features rail-to-rail inputs and an open-drain output configuration. Key electrical specifications include a maximum input offset voltage of ±2mV across the industrial temperature range (-40°C to +125°C), a typical propagation delay of 100ns, and high power-supply rejection ratio (PSRR) of 95dB.

Comparators Feature Summary

• Features fault-tolerant inputs capable of withstanding voltages up to 6V without damage or output phase inversion.
• Provides low input bias current and low input offset voltage for accurate precision voltage monitoring.
• Offers open-drain outputs that can be pulled up below or beyond the supply voltage for logic translation.

Comparators Applications

• Appliances
• Building automation
• Factory automation and control
• Motor drives
• Infotainment and cluster

Comparators Procurement Notes

Verify the specific ordering suffix 'DR' corresponds to the SOIC-14 tape-and-reel packaging format required for automated assembly. Confirm the component matches the open-drain output variant within the TLV902x family, distinct from the push-pull TLV903x series. Ensure the industrial temperature rating aligns with system environmental requirements before finalizing procurement.

Comparators Selection Notes

Select this component when designing circuits requiring multiple comparators with precise voltage threshold detection in noisy environments. The open-drain output allows flexible pull-up voltage selection, making it suitable for interfacing with different logic families. Consider the low quiescent current for battery-powered applications where power efficiency is critical alongside signal integrity.

Comparators Part Context

This part belongs to the TLV902x and TLV903x precision comparator family designed for harsh, noisy environments. While the TLV903x variants feature push-pull outputs, the TLV902x specifically utilizes open-drain outputs. The family shares common characteristics such as rail-to-rail inputs and low power consumption, but output stage differences dictate specific application suitability.

Comparators Replacement Considerations

TLV9034DR serves as a functional substitute if push-pull outputs are acceptable instead of open-drain. Other single or dual channel variants like TLV9020 or TLV9022 may replace this part if fewer channels are sufficient, provided pinout compatibility is verified.
