TLV1812DDFR

Comparators Overview

The TLV1812DDFR is a dual-channel analog comparator from the Texas Instruments TLV181x family, housed in an 8-pin SOT-23 package. It features rail-to-rail inputs and push-pull outputs. The device operates on a supply voltage range of 2.4V to 40V with a quiescent current of 5µA per channel. Key electrical specifications include a typical input offset voltage of 500µV, a propagation delay of 420ns, and an input bias current of 150fA. It supports an operating temperature range from -40°C to +125°C.

Comparators Feature Summary

• Rail-to-rail input capability allows signal voltages to extend slightly beyond the supply rails without phase inversion.
• Integrated Power-On Reset (POR) ensures output remains in a known state during power-up and power-down sequences.
• Push-pull output stage provides both sourcing and sinking capabilities for driving loads like LEDs or MOSFET gates.

Comparators Applications

• Appliances
• Factory automation and control
• Motor drives

Comparators Procurement Notes

Verify the specific ordering suffix DDFR corresponds to the SOT-23-8 package configuration required for your design. Confirm that the component meets all functional safety documentation requirements if applicable to your system. Ensure compatibility with the specified thermal metrics and absolute maximum ratings during integration.

Comparators Selection Notes

Select this part when high-voltage operation up to 40V is required alongside low power consumption. The push-pull output distinguishes it from the open-drain TLV182x variants. Consider the 500µV offset voltage for precision applications and verify that the SOT-23 package dimensions fit the PCB layout constraints.

Comparators Part Context

This component belongs to the TLV181x and TLV182x family of micro-power comparators. The family offers single, dual, and quad channel options with either push-pull or open-drain outputs. All devices share common characteristics such as rail-to-rail inputs, low quiescent current, and integrated Power-On Reset functionality.

Comparators Replacement Considerations

The TLV1812DDFRQ1 is an automotive-grade variant within the same family offering similar electrical performance but with AEC-Q100 qualification.
