Product Details

LM8261M5X/NOPB – TI Single RRIO High Output Current Operational Amplifier

LM8261M5X/NOPB is a Texas Instruments single rail-to-rail input and output operational amplifier designed for high-output-current signal buffering and capacitive-load drive applications. With 24MHz gain-bandwidth product, 35V/µs slew rate, 2.7V to 32V supply range and compact 5-pin SOT-23 package, it is suitable for TFT-LCD VCOM drivers, ADC buffers, high-side or low-side sensing, headphone amplifiers and general-purpose analog signal paths.

FunctionSingle RRIO Op Amp
GBWP24MHz
Slew Rate35V/µs
PackageDBV / SOT-23-5

Engineering note: Verify the latest TI datasheet, output load, capacitive-load stability, power dissipation, supply decoupling and PCB layout before production approval.

Component Overview

LM8261M5X/NOPB belongs to the TI LM8261 family of single RRIO operational amplifiers. It is designed for applications that need wide supply-voltage operation, high output drive, fast signal response and stable operation with capacitive loads.

TomatoElec view: LM8261M5X/NOPB is useful when a design needs a compact op amp that can buffer signals and drive heavier output loads than ordinary small-signal amplifiers. Its value comes from rail-to-rail input/output behavior, 24MHz bandwidth, high output current capability and unlimited capacitive-load drive.

Circuit Function & Design Role

Signal Buffering

Buffers analog signals between sensors, ADC inputs, display circuits and downstream analog stages.

Capacitive Load Drive

Supports capacitive-load drive applications such as display panel VCOM buffering and long analog traces.

High Output Current

Provides stronger output drive for loads that require more current than a typical low-power op amp can provide.

Wide Supply Operation

The 2.7V to 32V supply range supports both low-voltage and higher-voltage analog system designs.

Application Scenarios

TFT-LCD VCOM Driver

Used as a high-current buffer for flat-panel display VCOM drive and related analog display circuits.

ADC Input Buffer

Buffers analog signals before ADC conversion, helping reduce source impedance and improve signal integrity.

High-Side / Low-Side Sensing

Can be used in sensing and monitoring circuits where rail-to-rail input and output behavior is useful.

Audio & Headphone Circuits

Applicable to headphone amplifier stages, audio buffers and medium-speed analog output circuits.

TomatoElec Quality & Supply Notes

As an in-stock independent distributor and electronic components supplier, TomatoElec supports LM8261M5X/NOPB sourcing for engineering samples, production replenishment, urgent replacement and BOM purchasing. For operational amplifiers, correct package, reel condition, manufacturer marking and original sourcing are important because the device affects analog signal accuracy, output drive and system stability.

  • Original component sourcing: support sourcing of original Texas Instruments operational amplifier ICs.
  • Inventory support: help confirm available stock, package condition, date code and shipment schedule.
  • Package verification: confirm the DBV / SOT-23-5 package and tape-and-reel carrier before shipment.
  • BOM matching: verify bandwidth, supply range, output drive, package, pinout and temperature requirements before approving any substitute.

Replacement & BOM Matching Guidance

LM8261M5X/NOPB should not be replaced only by matching the single op amp category. Engineers should compare RRIO behavior, supply voltage range, GBWP, slew rate, output current, capacitive-load stability, output swing, input noise, package, pinout and thermal performance.

Selection tip: If the original design uses the LM8261 for capacitive-load drive or VCOM buffering, replacement must be validated under real load conditions. A common low-power op amp may oscillate, slew too slowly or fail to provide enough output current.

FAQ

What is LM8261M5X/NOPB used for?
It is used for TFT-LCD VCOM driving, ADC buffering, analog signal conditioning, capacitive-load drive, high-side or low-side sensing, headphone amplifiers and general-purpose signal buffering.
Is LM8261M5X/NOPB rail-to-rail?
Yes. LM8261 is a rail-to-rail input and output operational amplifier, supporting wide supply-voltage operation and flexible signal swing.
Why is capacitive-load drive important for LM8261M5X/NOPB?
Capacitive-load drive helps the op amp remain useful in circuits such as display buffers, long traces and high-capacitance analog nodes where ordinary op amps may become unstable.
Can TomatoElec support LM8261M5X/NOPB sourcing?
TomatoElec can support LM8261M5X/NOPB inquiry, inventory confirmation, BOM sourcing and shipment coordination.

Final Selection Summary

LM8261M5X/NOPB is a compact RRIO operational amplifier for designs requiring high output current, capacitive-load drive, 24MHz bandwidth and a wide 2.7V to 32V supply range.

TomatoElec recommendation: Use LM8261M5X/NOPB when the BOM requires Texas Instruments RRIO op amp performance, high output current, unlimited capacitive-load drive and DBV / SOT-23-5 packaging.
