TLV2461QDRG4Q1

Instrumentation, Op Amps, Buffer Amps Overview

The TLV2461QDRG4Q1 is a single-channel, low-power operational amplifier from Texas Instruments, designed for automotive applications under the AEC-Q100 qualification standard. It features rail-to-rail input and output capabilities, enabling full signal swing across the supply range. The device operates on a single supply voltage ranging from 2.7 V to 6 V, with a maximum dual supply of 3 V per side. Key electrical specifications include a gain-bandwidth product of 6.4 MHz, a slew rate of 1.6 V/µs, and an input offset voltage of 1.5 mV. It draws 550 µA of quiescent current per channel and provides an output current capability of 80 mA. The common-mode rejection ratio is 85 dB, and it functions reliably within a temperature range of -40°C to +125°C in an 8-pin TSSOP package.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Rail-to-rail input and output operation allows for maximum dynamic range in low-voltage systems.
• Automotive-grade reliability ensured through AEC-Q100 qualification for sustained performance in harsh environments.
• High drive capability supports direct interfacing with loads requiring significant current without external buffering.

Instrumentation, Op Amps, Buffer Amps Applications

• Battery-powered automotive sensor interfaces
• Active filter circuits in infotainment systems
• Signal conditioning for vehicle monitoring subsystems

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'G4' indicates lead-free and RoHS-compliant packaging standards as defined by Texas Instruments. Confirm that the 'Q1' designation aligns with your project's required automotive grade and reliability specifications. Ensure the TSSOP-8 footprint matches your PCB layout constraints. Cross-reference the datasheet revision date to ensure compatibility with your design requirements.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a single op-amp with rail-to-rail I/O is needed in a compact TSSOP-8 package. It is suitable for designs requiring moderate bandwidth (6.4 MHz) and high output drive (80 mA) at low power consumption (550 µA). Consider alternatives if higher precision or lower noise density is required, as this part prioritizes drive strength and low voltage operation over ultra-low noise performance.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the TLV2461A family of low-power operational amplifiers. The 'Q' prefix denotes automotive qualification, while 'G4' specifies the green (RoHS compliant, no Sb/Br) tape and reel packaging. It is part of Texas Instruments' broader portfolio of analog signal chain components designed for robust performance in industrial and automotive sectors.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct pin-compatible replacements within the same family include the TLV2461AQDRQ1. For non-automotive applications, the TLV2461ADR may serve as a functional equivalent, though it lacks the Q1 automotive qualification. Verify that any substitute meets the 6 V maximum supply voltage and 80 mA output current requirements.
