TL331IDBVR

Comparators Overview

The TL331IDBVR is a single differential comparator manufactured by Texas Instruments, housed in an SOT-23-5 surface-mount package. It operates within a supply voltage range of 2V to 36V for single supplies or ±1V to ±18V for dual supplies. The device features an open-collector, rail-to-rail output and exhibits a maximum input offset voltage of 5mV at 30V. Key electrical characteristics include a maximum input bias current of 0.25µA at 5V, a typical output current of 20mA, and a maximum static current of 700µA. It functions reliably across a temperature range of -40°C to 85°C.

Comparators Feature Summary

• Provides standard general-purpose comparison functionality with open-collector outputs.
• Supports wide single-supply operation from 2V up to 36V.
• Features rail-to-rail output capability for maximum signal swing.
• Delivers low input bias current for high-impedance sensing applications.

Comparators Applications

• General-purpose threshold detection circuits
• Voltage monitoring systems
• Signal conditioning interfaces

Comparators Procurement Notes

Verify the specific suffix 'E4' against the ordered part number, as it indicates RoHS compliance and lead-free status. Confirm the active status, as some listings indicate this variant may be obsolete with replacement options available. Ensure the SOT-23-5 package matches the PCB footprint requirements. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.

Comparators Selection Notes

Select this component when a wide supply voltage range up to 36V is required alongside low power consumption. The open-collector output necessitates an external pull-up resistor, which allows flexibility in interfacing with different logic levels. Consider the 5mV input offset voltage specification for precision requirements. Verify that the operating temperature range of -40°C to 85°C meets the environmental constraints of the target application.

Comparators Part Context

The TL331 belongs to a family of single comparators from Texas Instruments, sharing architectural similarities with the TL331B and TL391B series. These devices are designed for cost-sensitive applications requiring reliable switching performance. The IDBVR designation specifically denotes the industrial temperature grade and the SOT-23-5 surface-mount packaging format used for compact board layouts.

Comparators Replacement Considerations

Public documentation identifies the TL331IDBVR as a direct substitute for the obsolete TL331IDBVRE4. Designers should verify pinout compatibility and electrical parameter equivalence before swapping components in existing designs.
