TLV7211AID

Comparators Overview

The TLV7211AID is a single-channel CMOS analog comparator manufactured by Texas Instruments, housed in an 8-pin SOIC package. It features rail-to-rail input capability and push-pull output stages. The device operates on a single supply voltage ranging from 2.7V to 15V or dual supplies of ±1.35V to ±7.5V. Key electrical specifications include a maximum propagation delay of 10µs, a typical quiescent current of 18µA, and a maximum input offset voltage of 5mV at 5V. The input bias current is typically 0.04pA at 5V, with common-mode rejection ratio (CMRR) and power supply rejection ratio (PSRR) values of 75dB and 80dB respectively.

Comparators Feature Summary

• Rail-to-rail input stage allows signal processing across the full supply voltage range.
• Push-pull output configuration provides strong drive capability without requiring external pull-up resistors.
• Low static current consumption supports battery-powered applications.
• High input impedance minimizes loading effects on preceding circuit stages.

Comparators Applications

• Threshold detection circuits
• Simple analog-to-digital conversion interfaces
• Over-voltage protection monitoring

Comparators Procurement Notes

Verify the specific suffix 'ID' confirms the SOIC-8 package variant rather than the DBVR SOT-23-5 version. Confirm RoHS compliance status matches current manufacturing standards. Ensure the operating temperature range aligns with system requirements, as industrial grades may differ from commercial variants. Cross-reference the datasheet revision date to ensure compatibility with latest electrical characteristics.

Comparators Selection Notes

Select this component when a low-cost, general-purpose comparator with rail-to-rail inputs is required. The push-pull output simplifies interface design compared to open-drain alternatives. Consider the 10µs propagation delay for timing-sensitive applications; faster options exist if nanosecond response is critical. The wide supply voltage range offers flexibility in systems using 3.3V or 5V logic levels.

Comparators Part Context

The TLV7211A series belongs to Texas Instruments' family of micro-power CMOS comparators. It serves as a successor or alternative to older LMC7211 devices, offering similar functionality in modern packages. The 'A' designation typically indicates improved electrical specifications over the base TLV7211 model. This part is designed for cost-sensitive consumer and industrial electronics where moderate speed and low power are prioritized.

Comparators Replacement Considerations

LMC7211BIM5X/NOPB is a documented substitute offering similar functionality in a different package format.
