Product details
Overview
LM7301IM5 from Texas Instruments is a rail-to-rail input-output operational amplifier in a 5-pin SOT-23 package, delivering 4.5 MHz gain-bandwidth, 0.56 mA supply current, and rail-to-rail output swing (0.07 V to 4.93 V at 5 V). It operates from 2.7 V to 32 V and supports portable instrumentation, ADC buffering, and active filtering.
For engineers reviewing the LM7301IM5 datasheet, LM7301IM5 pinout, LM7301IM5 application, or LM7301IM5 equivalent, key selection criteria include its >rail-to-rail input common-mode range (−0.1 V to 5.1 V), high PSRR (104 dB), low input bias current (0.01 nA typ), 21 V/µs slew rate, and SOT-23 thermal resistance (325 °C/W).
Technical Context
The LM7301IM5 employs a slew-boosted architecture enabling 21 V/µs large-signal slew rate above 150 mV input differential voltage, while maintaining 0.5 V/µs natural slew for small signals (<20 mV). Its input stage accepts voltages beyond the supply rails (−0.1 V to 5.1 V at 5 V), eliminating CMVR concerns in single-supply sensor interfaces.
It achieves rail-to-rail output swing with <0.12 V headroom at 10 kΩ load and delivers 75 mA short-circuit current. The 540 GΩ input resistance and 93 dB CMRR support precision DC-coupled signal conditioning without external bias networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 4.5 MHz - enables stable unity-gain buffer or 10× gain amplification up to ~450 kHz. |
| Supply current | 0.56 mA - allows battery-powered operation for >1000 hours on a 500 mAh cell at 5 V. |
| Input CMVR | −0.1 V to 5.1 V at 5 V - accepts signals below ground or above V+, simplifying level-shifting in mixed-supply systems. |
| Rail-to-rail output | 0.07 V to 4.93 V at 5 V - maximizes dynamic range for low-voltage ADC drivers and DAC buffers. |
| PSRR | 104 dB - rejects power supply noise, critical for clean analog front-ends in noisy digital environments. |
| Slew rate | 21 V/µs - supports fast settling of 10 V step responses in <0.5 µs, suitable for pulse amplification. |
| Input bias current | 0.01 nA typ - minimizes voltage error across high-impedance sources (e.g., pH electrodes, photodiodes). |
Pinout & Package
LM7301IM5 uses the DBV (SOT-23) 5-pin package: 2.90 mm × 1.60 mm body, 0.95 mm height, gull-wing leads. Thermal resistance is 325 °C/W (RθJA).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Output | Amplified signal node; drives loads ≥10 kΩ directly; capable of ±75 mA short-circuit current. |
| 2 (V−) | Negative supply | Ground reference in single-supply mode; accepts −0.3 V to (V+) + 0.3 V per absolute max ratings. |
| 3 (+IN) | Noninverting input | High-impedance node (540 GΩ); accepts common-mode voltages beyond rails (−0.1 V to 5.1 V at 5 V). |
| 4 (−IN) | Inverting input | High-impedance node; used for feedback network connection in standard op-amp configurations. |
| 5 (V+) | Positive supply | Accepts 2.7 V to 32 V; bypass capacitor required close to pin to suppress supply noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Slew-boosted architecture | Delivers 21 V/µs large-signal response without sacrificing small-signal linearity (0.5 V/µs natural slew). |
| Ultra-low input bias current | 0.01 nA typical enables direct interfacing with high-Z sensors (e.g., piezoelectric transducers) without guard traces. |
| Extended common-mode input range | Operates with inputs 0.1 V below V− or 0.1 V above V+, removing need for external level-shifters in rail-referenced circuits. |
| High open-loop gain | 97 dB ensures <0.01% gain error in unity-gain buffer applications with 10 kΩ load. |
| Low input voltage noise | 36 nV/√Hz at 1 kHz supports low-noise amplification of microvolt-level biomedical or audio signals. |
Applications
| Portable Instrumentation | ADC Signal Conditioning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2461IDBVR | Lower GBW (6.4 MHz), higher supply current (550 µA), same SOT-23-5 package and rail-to-rail I/O. | Better for higher-speed AC-coupled apps; less suitable for ultra-low-power battery use due to 10× higher quiescent current. | Choose TLV2461IDBVR when bandwidth >5 MHz is required and supply current <1 mA remains acceptable. |
| OPA333AIDBVR | Zero-drift architecture, 0.1 µV/°C offset drift, 35 µA supply current, but only 350 kHz GBW and 16 V max supply. | Superior for precision DC measurements (e.g., weigh scales); unsuitable for >100 kHz signal paths or 30 V industrial supplies. | Choose OPA333AIDBVR when microvolt-level offset stability over temperature outweighs speed and voltage range needs. |
Compared with TLV2461IDBVR and OPA333AIDBVR, the LM7301IM5 uniquely balances 4.5 MHz bandwidth, 0.56 mA consumption, and 32 V operation in SOT-23-making it optimal for portable, wide-supply, medium-speed analog signal chains where drift and ultra-low noise are secondary to power/speed trade-offs.

FAQ
What is the maximum supply voltage rating for the LM7301IM5?
The LM7301IM5 has an absolute maximum supply voltage (V+ − V−) of 35 V, with recommended operating range from 2.7 V to 32 V. Operation at 32 V is fully characterized per datasheet Section 5.7, including output swing (0.16 V to 29.8 V at 25°C) and PSRR (104 dB). Exceeding 35 V risks permanent damage per Absolute Maximum Ratings.
Does the LM7301IM5 support true rail-to-rail input operation?
Yes, the LM7301IM5 provides greater than rail-to-rail input common-mode voltage range: −0.1 V to 5.1 V at 5 V supply, and −0.1 V to 30.1 V at 30 V supply. This allows input signals to extend 0.1 V below V− or 0.1 V above V+, eliminating the need for external level-shifting circuitry in single-supply sensor interfaces.
What is the thermal performance of the LM7301IM5 in its SOT-23 package?
The LM7301IM5 in DBV (SOT-23-5) package has a junction-to-ambient thermal resistance (RθJA) of 325 °C/W under standard JEDEC test conditions. This value assumes a 1-inch² copper pad on a 1-layer board; actual board layout significantly impacts thermal performance, and TI recommends using 0.1-μF ceramic bypass capacitors adjacent to V+ and V− pins to minimize self-heating effects.
Can the LM7301IM5 drive capacitive loads without instability?
The LM7301IM5 is specified to drive large capacitive loads robustly, with typical applications including ADC input buffering where 10–100 pF capacitance is common. Its internal compensation and slew-boost architecture maintain stability without requiring external isolation resistors, though layout best practices (short traces, local bypassing) are essential to preserve phase margin at high frequencies.
How does the LM7301IM5's input bias current compare to other SOT-23 op-amps?
The LM7301IM5 features an exceptionally low input bias current of 0.01 nA (10 pA) typical at 25°C-two orders of magnitude lower than many general-purpose SOT-23 op-amps (e.g., LMV321: ~100 nA). This enables accurate amplification of signals from ultra-high-impedance sources like photodiodes or electrochemical sensors without significant DC error.
