TLV1812DR

Comparators Overview

The TLV1812DR is a dual-channel analog comparator from the Texas Instruments TLV181x family, housed in an 8-pin SOIC 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 parameters include a typical propagation delay of 420ns, input offset voltage of ±0.5mV, and input bias current of 150fA. It supports an ambient 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 until minimum supply voltage is reached.
• Push-pull output stage provides high drive capability for loads such as LEDs or MOSFET gates.

Comparators Applications

• Appliances
• Factory automation and control
• Motor drives

Comparators Procurement Notes

Verify the specific ordering suffix 'D' corresponds to the SOIC-8 package when sourcing. Confirm that the component meets the required automotive or industrial specifications if applicable, as standard versions may differ from Q1 variants. Ensure the datasheet revision matches the design requirements for thermal and electrical characteristics.

Comparators Selection Notes

Select this part for applications requiring wide supply voltage operation up to 40V with low power consumption. The push-pull output is suitable for direct load driving without external pull-up resistors. Consider the TLV1822 variant if open-drain outputs are preferred for logic level translation or wired-OR configurations.

Comparators Part Context

This component belongs to the TLV18xx family of micro-power comparators designed for portable, automotive, and industrial systems. The family includes single, dual, and quad channel options with both push-pull and open-drain output choices, all sharing similar electrical performance profiles.

Comparators Replacement Considerations

TLV1812PW (TSSOP-8), TLV1812DGK (VSSOP-8), TLV1812DSGR (WSON-8). Verify pinout compatibility and package dimensions before substitution.

Comparators FAQ

How should unused inputs be handled?

Do not tie unused inputs together. Connect them to a valid voltage within the specified input range that provides at least 50mV differential voltage to prevent chatter.

What is the maximum input voltage relative to the supply?

The input voltage range extends from 0.2V below V- to 0.2V above V+. Signals exceeding these limits must be current-limited.
