Product Details
LM321MFX/NOPB – TI Single 30V, 1MHz Operational Amplifier
LM321MFX/NOPB is a Texas Instruments single low-power operational amplifier designed for compact analog signal conditioning and control circuits. With 1MHz gain-bandwidth product, 430µA typical supply current, input common-mode range including ground and a small 5-pin SOT-23 package, it is suitable for sensor interfaces, voltage followers, active filters, portable electronics and general-purpose analog front-end designs.
Engineering note: Verify the latest TI datasheet, supply voltage, input common-mode range, output swing, capacitive load and PCB layout before production approval.
Component Overview
LM321MFX/NOPB belongs to the TI LM321 family of single operational amplifiers. It is designed as a space-saving single version of the LM324-style amplifier architecture and is suitable for low-power analog circuits where a single amplifier channel is required.
Circuit Function & Design Role
Amplifies, buffers or filters low-frequency analog signals from sensors, control loops and monitoring circuits.
Can be used as a voltage follower to isolate signal sources from ADC inputs or downstream circuits.
The low typical supply current helps reduce power consumption in portable and always-on systems.
The input common-mode range includes ground, making it useful in many single-supply analog designs.

TomatoElec Quality & Supply Notes
As an in-stock independent distributor and electronic components supplier, TomatoElec supports LM321MFX/NOPB sourcing for engineering samples, production replenishment, urgent replacement and BOM purchasing. For operational amplifiers, correct package, manufacturer marking, reel condition and original sourcing are important because the device affects analog signal accuracy 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 before shipment.
- BOM matching: verify bandwidth, supply range, package, pinout and temperature requirements before approving any substitute.
Replacement & BOM Matching Guidance
LM321MFX/NOPB should not be replaced only by matching the single op amp category. Engineers should compare supply voltage range, GBW, slew rate, input common-mode range, output swing, offset voltage, input bias current, package, pinout and stability with capacitive loads.
