Product details
Overview
LM7341MF/NOPB from Texas Instruments is a rail-to-rail input/output operational amplifier in a 5-pin SOT-23 package, delivering 4.6 MHz gain bandwidth, 1.9 V/µs slew rate, and ±15V supply operation. It supports −40°C to 125°C industrial temperature range and enables high-side sensing, photodiode biasing, and sensor output buffering with full rail-to-rail swing (−14.84V to +14.86V at ±15V).
For engineers reviewing the LM7341MF/NOPB datasheet, LM7341MF/NOPB pinout, LM7341MF/NOPB application, or LM7341MF/NOPB equivalent, key selection considerations include its rail-to-rail CMVR (−15.3V to +15.3V), low 0.7 mA supply current, high PSRR (106 dB), wide 2.7V–32V supply range, and verified performance across ±15V, ±5V, and 2.7V rails.
Technical Context
The LM7341MF/NOPB employs a CMOS input stage enabling greater-than-rail common-mode voltage range and low input bias current (±250 nA max at ±15V). Its internal compensation ensures stable unity-gain operation while driving capacitive loads up to 1000 pF with ≥30° phase margin.
It operates across split supplies (±2.5V to ±15V) or single supplies (2.7V to 32V), maintaining consistent open-loop gain (≥115 dB CMRR, ≥106 dB PSRR) and low distortion (−65 dB THD+N at 10 kHz) - critical for precision signal conditioning in automotive and industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth | 4.6 MHz - supports stable closed-loop operation up to ~1 MHz with moderate gain, suitable for active filters and fast sensor interfaces. |
| Slew Rate | 1.9 V/µs - enables clean 10 kHz sine wave output at ±12V swing without slewing distortion. |
| Supply Range | 2.7V to 32V - accommodates battery-powered systems (e.g., 3.3V/5V) and industrial rails (±15V) without redesign. |
| Input CMVR | −15.3V to +15.3V at ±15V - allows direct connection to signals beyond supply rails, essential for high-side current sensing. |
| Output Swing | −14.84V to +14.86V at ±15V - delivers >99% of full rail, minimizing headroom loss in analog front-ends. |
| Supply Current | 0.7 mA typical - enables low-power operation in always-on sensor nodes or portable equipment. |
| CMRR | 115 dB at ±15V - rejects common-mode noise in noisy industrial environments, preserving signal integrity. |
Pinout & Package
LM7341MF/NOPB uses a 5-pin SOT-23 (TinyPak) package with 325°C/W thermal resistance, optimized for space-constrained PCB layouts and high-density routing near signal sources.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Inverting Input (−) | Differential input node | Accepts signal referenced to ground or virtual ground; supports rail-to-rail common-mode input down to −15.3V. |
| Non-Inverting Input (+) | Differential input node | Enables high-impedance sensing of signals up to +15.3V relative to VEE, ideal for high-side monitoring. |
| Output | Amplified signal source | Drives loads to within 135 mV of either rail (at ±15V, RL = 10 kΩ), supporting low-headroom ADC interfacing. |
| V+ | Positive supply terminal | Accepts up to +32V or +15V in split-supply mode; internal ESD protection rated to 2000V HBM. |
| V− | Negative supply terminal | Accepts down to −32V or −15V; enables true bipolar operation and below-ground current sensing. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input CMVR | Extends usable input range beyond supply rails (±15.3V at ±15V), eliminating level-shifting in high-side sensing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462IDR | Lower GBW (6.4 MHz), higher supply current (650 µA typ), rail-to-rail I/O, but only rated to 125°C (not −40°C). | Limited to commercial-temperature industrial use; lacks extended cold-start capability. | Select when higher bandwidth is needed and operating temperature stays above −20°C. |
| OPA333AIDBVR | Zero-drift architecture, 0.1 µV/°C offset drift, 350 kHz GBW, 17 µA supply current - optimized for DC precision, not speed. | Better for low-frequency sensor bridges; unsuitable for >100 kHz signal paths or photodiode AC response. | Choose for microvolt-level DC stability where bandwidth <50 kHz suffices. |
Compared with TLV2462IDR and OPA333AIDBVR, LM7341MF/NOPB uniquely balances wide temperature range (−40°C to 125°C), high speed (4.6 MHz), rail-to-rail operation, and ultra-low power (0.7 mA) - making it optimal for automotive and ruggedized portable instrumentation where all three attributes are simultaneously required.

FAQ
What is the maximum supply voltage rating for LM7341MF/NOPB?
The absolute maximum supply voltage (V+ to V−) for LM7341MF/NOPB is 35V, with recommended operating range from 2.5V to 32V. At ±15V operation, it delivers full rail-to-rail output swing and 4.6 MHz gain bandwidth. Exceeding 32V risks exceeding junction temperature limits due to power dissipation in the 5-pin SOT-23 package.
Does LM7341MF/NOPB support single-supply operation?
Yes, LM7341MF/NOPB supports true single-supply operation from 2.7V to 32V. Its rail-to-rail input extends to V− −0.3V and V+ +0.3V, and output swings within 135 mV of each rail at 10 kΩ load - enabling use in 3.3V or 5V systems without level-shifting circuitry.
Can LM7341MF/NOPB be used as a comparator?
Yes, LM7341MF/NOPB can function as a comparator, with propagation delay of 12 µs at 1V overdrive (VS = 30V). However, it is not optimized for this role: differential input voltage must stay within ±15V to avoid damage, and no internal hysteresis or open-collector output is provided. For dedicated comparator functions, TI recommends TLV3501 or LM393.
What is the input bias current specification for LM7341MF/NOPB at ±15V supply?
At ±15V supply and TA = 25°C, LM7341MF/NOPB exhibits input bias current of −250 nA to −110 nA (typical −110 nA) at VCM = −14.5V, and +40 nA to +90 nA (typical +80 nA) at VCM = +14.5V. This asymmetry reflects CMOS input stage behavior and is confirmed in the ±15V Electrical Characteristics table.
Is LM7341MF/NOPB RoHS-compliant and lead-free?
Yes, LM7341MF/NOPB is RoHS-compliant and lead-free. The "NOPB" suffix explicitly denotes lead-free packaging per TI's standard product marking convention, and the device meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) requirements for surface-mount assembly.
